Sir initially this subject i used to feel difficult.....but now it is my favourite subject. SIR...WISH U HAPPY TEACHERS DAY. Thank u for being such a wonderful teacher for all of us.
I don't understand how someone could dislike your teaching. Anway Sir! i have been following your teaching for 6 days in a row and i have loved it all and have understood it far better than before. All thanks to you. please keep teaching! lots of love from North-East India.
May GOD provide a special teacher like you in every school and college so that the Indian Education system gets a new reform of not by-hearting subjects and deeply understanding them. THANK YOU
Sir aapki teaching best hai ....even I did joined coaching then also my concepts were not clear ....by listening your lectures I am able to solve questions perfectly thanku sir .. I think each and every teacher must explain us like you and should revise concept at the starting of lecture
Till now I have watched all 5 lectures it's 6th one..... Everything is going so well... Thanks again sir 😊 u clear my doubt regarding this subject..... I've never prepare for this subject thinking it's a tough one..but your lectures gave me the confidence that I too can prepare well in the subject.....it's not that tough as I used to consider..!!
First thank you heartily sir. sir when I was start study this subject, that time I feel it was very difficult and confusing 😕 than i came on u tube and search for lecture videos then I got your video till I feel this subject is easy. I feel easy because your talent and also your syllabus pattern to teach thank you so much sir
hi sir firstly, great thanks for give your precious time for students , by your teachng class i learned what is SNS at this time i have no words for says thanks ..... i seeing your whole video ....Again a greatulll Thanks..........
Sir You really are an amazing teacher!!! I am so grateful to you for teaching me all of this so easily that it doesn't feel like just memorizing a bunch of stuff but rather understanding the cause and result accurately so there is no scope of forgetting. I am so grateful to Saraswati Mata that you are my mentor for this subject and you made this very much easier than it was. Thank you very much sir. I pray to Ram Ji that all of your work gets most recognition and may you and this channel reach many new heights, each surpassing the previous ones Jai Siya Ram
Thank You very much sir!!! I am so grateful to you for teaching this subject in such an easy way. Sir, earlier a quest from this topic came in my mid sem and I was unable to do it cause I didn't watch this video but now I took the paper out and after this class I was easily able to solve the quest so I am now ready on this quest for my end sem tomorrow and I am confident that after I complete more topics, I will surely do a lot better in my End Sem of Signals and Systems tomorrow, all thanks to my Parents, my Teachers and my Saraswati Mata Jai Siya Ram
Sir,this is going to my 2nd attempt in GATE exam.,& the way u r teaching is the best lecture on this subject i hv seen till now.it helps a lot me to make more clarity on this subject.So we requesting u to upload videos on Laplace & Z-transform too..please sir
Hello Babul, Definitely we will upload the content you are looking for, but we are following a proper sequence for better understanding of students. Thanks a lot & all the best..👍👍
Very very good explanation sir. I have a doubt, in periodic signals what is the difference between w0(fundamental frequency) and just f(frequency in Hz)?
Sir, to check the periodicity of any signal when it comes to calculate the ratio, is there any rule that the ratio must be in the form of t2/t1=t3/t2=t1/t3?
Priya Chaudhary Either go with the graph of tanx or write tanx= sinx/cosx & then give a shift of integer multiples of π in both numerator and denominator...
Sir jaise apna btaya agr hme pie or exponential mile then signal is aperiodic,agr hme signal mai imaginary part mile then it will be periodic or aperiodic?
Sir aperiodic signal pe please examples bataye apne sin aur cos ka jaise bataya wo hmaesha periodic hongi waise he aperiodic pe b kya ap example dikha saktay ho
Sir! For the combination of periodic signals, you mentioned that the ratio of any two fundamental periods should be a rational number. Still, taking the example you dealt with x(t)=4 cos(2pit)+3sin(6t)+5cos(60pit). If we take the Fundamental period of both cos functions individually, then the resulting periods would not contain any expression of pi and their ratio will be a rational number, implying that the signal would be periodic. Still, you mentioned in the lecture that it is not periodic. Could you please help??
3no terms ka ratio rational huna zarori hy for periodicity agar aik bhi irrational huga to whole signal combination not periodic ( aperiodic) hu jaye ga
sir mujhe a slight doubt he,if x(t)=cos6t,,this type ki signal hotI to kya e periodic hoti or nehi,bqs idhar to time period T=(2pai/6)=(pai/3)=irrational no,sir pls clear it
Atanu Laha Single continuous time signal ka period kuchh bhi ho sakta hai, rational ya irrational value se fark nahi padta, ye jitne constant time ke baad baar baar repeat hoga, wo iska period hoga. jab ek se jyada signals se mil kar koi signal form hota hai, to unke time periods ka ratio rational hona chahiye, nahi to overall period aisa nahi mil sakta jisme individual period se devide karne par integer mile.
The value π is an irrational number. It cannot be represented exactly as a rational number; that is, a fraction with numerator and denominator both integers. The decimal representation of π is a never ending, never repeating string of digits. In grade school we learned that a simple approximation for π is 22/7.
Hello Mukund, Actually 22/7 is the approximate value of π, π is not exactly equal to that. So even 22/7 is a rational number still we take π as irrational..👍
Sir initially this subject i used to feel difficult.....but now it is my favourite subject. SIR...WISH U HAPPY TEACHERS DAY. Thank u for being such a wonderful teacher for all of us.
Thanks a lot.
Feel free to ask about any point, that is not clear..👍👍

sir u clear all the basic concepts
thnku so much sir
Nice explanation sir thank for teaching us
Suprb sir
😊👌
Niraj sir fundamental time period ka LCM aur fundamental frequency ka HCF kyu hota hai? iska reason kya hai?
Thankyou sir
Thank you so much 🥰
Great sir 👍
You are best sir
which other subjects neeraj also teach?
Sakshssy ❤
@@tejvratsinghchauhan7591 You both are brother and sister ?
Plz provide more lecture sir
Ur lecture is very important for us...
Very good sir 😊 thanks
in that even part of u(t) function is not defined or equal to 1/2?
Thank you so much sir
@ 23:59 I think Φ is phase angle
sir you are best
Sir you have not covered doublet function till now.
thnak you sir
Omega ka ratio of rational hoga,then periodic ho Sakta hei kya ???
Very nice explanation sir
Agrr t me square wali term of to ans.. kya aayega periodic ya ohir aperiodic??
Great sir
VIBING ON INTRO OF THIS VIDEO
Sir signal and system ka question kon se book se kare?
Marvellous
Superb...
Sir T1/T3 ka ratio nikalege to 30 aayega to ye to periodic hoga kya pls answer me ????/
Sir jab ap continuous time KY liy koi topic parhaty hen to sath sath discreate time KY liy bhi parha dia Karyn same topic se related..
Mast sir
Thank u sir ...
This is very much helpfull ..
thank you sir.. nice explanation..
Very very good explanation sir. I have a doubt, in periodic signals what is the difference between w0(fundamental frequency) and just f(frequency in Hz)?
hello sir,
the lectures are fabulous.but there is only module is avilable.
So how can i get another modules of this course?
Himanshu khatri
hello dear. Lectures will be uploaded here only, 3 more lectures have been uploaded recently, hope u hv seen them.
Please sir give me answer sir I very like your methodology
Sir with due respect W is not frequency. That's angul momentum
W(omega)= 2πf
Correct me if I am wrong
Sir, to check the periodicity of any signal when it comes to calculate the ratio, is there any rule that the ratio must be in the form of t2/t1=t3/t2=t1/t3?
Sir is it necessary that the ratios of time periods should be always equal for the combined signal to be periodic (T2/T1)=(T3/T2)=(T1/T3)??
Sir how we check the periodicity of tan t and cot t.
Priya Chaudhary
Either go with the graph of tanx or write tanx= sinx/cosx & then give a shift of integer multiples of π in both numerator and denominator...
neeraj raj
Thanku sir
Sir jaise apna btaya agr hme pie or exponential mile then signal is aperiodic,agr hme signal mai imaginary part mile then it will be periodic or aperiodic?
Ruchi Madaan
frequency is a real quantity, it should not contain imaginary terms, if you have any such example then send it..
At 14:05 you said that u(t) = 1 for t>0 but in books it is mentioned that u(t)=1 for t>=0
Yha both r right..👍🏾
Yeah. It is a point of discontinuity. Having both 0 and 1 at t=0
Sir aperiodic signal pe please examples bataye apne sin aur cos ka jaise bataya wo hmaesha periodic hongi waise he aperiodic pe b kya ap example dikha saktay ho

Discrete ke liye bhi time period btaiye sir...Thankew sir....🙏🙏🙏🙏
Thanku so much sir
Sir can you plz add notes too
Thank you sir.... What about discrete signal sir??
Jibin V
wait till the next 2 videos, we'll be dealing with all the operations, properties, periodicity, energy and power of discrete time signals..👍
neeraj raj thank you so much sir
Hii Sir I am Aktu student, what is enough for me these series,
Everything bro..
Thanks sir
sir mujhe a slight doubt he,if x(t)=cos6t,,this type ki signal hotI to kya e periodic hoti or nehi,bqs idhar to time period T=(2pai/6)=(pai/3)=irrational no,sir pls clear it

Sir 22/7 is a rational no. By mistake you wrote that it is irrarational.π is irrational and it is not exactly equal to 22/7

The decimal representation of π is a never ending, never repeating string of digits. In grade school we learned that a simple approximation for π is 22/7.
Sir please give us some homework problem
Please sir power system ki vidio bhi start kijiye....
Sir 22÷7=3.142857142857142857............ periodic ,,,Please Reply sir then confirm
Hello Mukund,
Actually 22/7 is the approximate value of π, π is not exactly equal to that.
So even 22/7 is a rational number still we take π as irrational..👍
@38:04 the value of pi is wrong. It is 3.14159265....
