Sir, instead of doing that whole process we can directly give s(t) to low pass filter as it contains both msg n carrier freq components so lpf allows only low freq components m(t)

See in testing we already have idea about transmitted signal so in that we can understand what is unwanted signal easily. Some other ways are based on frequency spectrum one can understand unwanted signal
In the second signal(unwanted signal) there is fc term which has higher frequency.. The low pass filter passes only low frequency signals. So it is unwanted..
Sir in coherent detection usually we give the modulated signal s(t) as input and at the output side we receive it as demodulated output m(t) but you chosen the wrong notation
the difference between coherent andsynchronous demodulation is, Coherentdetection uses a locally generated carrier whereas synchronous doesn't require a local carrier generator, in stead of that it is having self extraction capability of Carrier signal.
@@EngineeringFunda sir, majorly it may not matter but before letting such expressions it is always better to say about your consideration, how you took as every topics are related to each other for relatively better learning it is needed.
Yes the sine or cos wave u can take any as it's analog signal but he has left the amplitude Am there either he should tell that I am taking here constant amplitude here it would help most of the students to know Clearly

Earlier we learned dsbsc to be Acx(t)cosWct . Here why we are not giving the Ac term first?
Same doubt bro...
@@AyushYadav-rq8ze bro if any signal contains wc-wm, wc+wm frequencies ,then its dsbsc signal, nothing to care about Ac term..
Excellent work sir
Love and happiness of students is my ultimate goal, God bless you 🙏, keep learning and keep progressing.
Ok sir tq so much
Sir you are doing great job. I wish we got professors like u in the college. My suggestion is only that to give time for the screenshot.
I am planning to give Class Notes on my android application engineering funda, it is free for all.
🤣

thank you so much Guru ji.
sir , what is the difference between coherent detector and synchronous detector ..both have same block diagram
both are same only
Sir plzz start emft ...ur teaching style is excellent.
It will come after 60days
Why so much late sir...
I have some other work pending
@@EngineeringFunda when will it come
Aap na hote to kya hota ... Thank you so much sir
It is my pleasure to tech my students.

Sir, how we will prove that...AM signal is recovered , irrespective of the percentage modulation by using this (synchronous detector)
Sir, instead of doing that whole process we can directly give s(t) to low pass filter as it contains both msg n carrier freq components so lpf allows only low freq components m(t)
Here s(t) has no carrier frequency since it is DSBSC , it contains only USB and LSB, so we have to give c(t) also
good explaination

Nice Explanation. One question: What is the difference between synchronous detection and coherent detection?
Both are same
Sir is coherent and synchronous detection are same??
thanks keep going
Thank u sir
Is it the same topic as the demodulation of dsbsc
Tq bro

Sir thanku for your videos I have a doubt sir how I will get to know that the signal is unwanted?
See in testing we already have idea about transmitted signal so in that we can understand what is unwanted signal easily. Some other ways are based on frequency spectrum one can understand unwanted signal
Thanku sir
In the second signal(unwanted signal) there is fc term which has higher frequency.. The low pass filter passes only low frequency signals. So it is unwanted..
explain the topic superheterodyne receiver sir
It is there in Analog communication playlist
Sir, please make video on costas loop and quadrature carrier multiplexing.
Quick comment:
synchronous detection (or demod) is same as coherent detection (demod)!
Synchronous means coherent
Can we take carrier signal as sine wave
Yes no issues with that
In this case too na
😀 yes
In that case, 2sinAsinB=cos(A-B)-cos(A+B)
Sir please explain the topic CARRIER RE-INSERTION METHOD OF DETECTION IN DSB-SC...
The expression for output of low pass filter in that is it Ac or Ac^2? plz rply fast
Where are u asking in the video??
At what time?
at 7:56
Synchronous detector and coherent detector are same or not sir
Same
@@EngineeringFunda thank u sir for clearing my doubt
Sir in coherent detection usually we give the modulated signal s(t) as input and at the output side we receive it as demodulated output m(t) but you chosen the wrong notation
It doesn't make any difference
Sir can u make video on demodulation of DSB-FC synchronous detection .plzn
It is AM only.
plz upload pcm and dm video
Next month I will upload complete digital communication lecture series
Synchronous detection and coherent detection aren't same? In book it's written they are same. Please clear my doubt.
the difference between coherent andsynchronous demodulation is, Coherentdetection uses a locally generated carrier whereas synchronous doesn't require a local carrier generator, in stead of that it is having self extraction capability of Carrier signal.
Hey madhurima i have some doubts can you help me
Tqqqqqqqq sooooo much sir
Your videos are like "water found in desert"
How tx and rx are matched of oscillator
With phase lock loop we do that.
give us the past exam papers before Monday pls
23 exam it more sufficient sir
Yes
Warbling effect in dsbsc
we r giving the s(t) as a input to the product modulator but written wrong there bro
What is frequency error here
constant phase error how solved
Same question, how is it solved
sir ur explanation is very confusing u should have taken m(t)=Am coswmt
It doesn't matter, dear
@@EngineeringFunda sir, majorly it may not matter but before letting such expressions it is always better to say about your consideration, how you took as every topics are related to each other for relatively better learning it is needed.

In this case too na
Why it is called coherent detection??
It has reference of local oscillator to extract original information.
