Thank you sir. I really got help from your videos. I would like to suggest adding numerical problems too. In all subjects. Just numerical videos.
I am adding that even as I find time.
Teaching way is very simple sir and we can understand simple manner..

u made it to look very simple
thx

Tq sir ,u elucidated very clearly
Your welcome 🙏
Yes kavya true
Got good knowledge...nice explained...
Thanks and welcome
Nice explanation is given for spread spectrum. In this you have given a block diagram of DSSS with PN sequence and chip generator blocks after phase modulation block. The original information in discreet form, is firstly modulated with chip generator to expand its base bandwidth .Then further it undergoes PSK or QPSK or anyother keying so that final cont signal is available for transmission, so shouldn't PSK block come after chip generator??
Is alteration of signal base bandwidth by PN code is done initially and then its phase keyed to be transmitted or phase shift keying is done initially then this is further SS modulated using PN codes? which order it takes place? Please do clarify this point sir.
It is XNOR operations in Waveforms
Sir pseudo noise sequence generation video plz
sir please upload videos on random process and noise in digital systems,
Thankyou 💝
Please make a video about the preamble basics, preamble chu sequence, simple preamble and calculation of Autocorrelation of Preamble. Thanks in advance. (Topics come under Communication Electronics)
Thank you
Your welcome
sir explain the topic Gram Schmidt Method, orthogonal basis concept and problems...
thank you soo much...
Nice Sir
Sir whether this content is enough for 8 mark questions? For sem exams?
Yeah
Sir you can add signal space representation in this playlist.
Waaailcome to couumm. plaaayyyyyiiiii....liiiist.I Biiiibii explaaaaaiiiiing ....
what is BW shuring of DSSS in that last segment?
How can one design a cdma system in real time ? If we’re sending a composite signal in the channel then how we can recover that as most of the system would normalise signal to -1 and 1. Can you explain this concept ?
Hi sir please share some videos on topics regarding multipath channels in wireless communication
Please..... thank you
Thanks
In DSSS, how does the increase of the spreading factor relate to bit rate error?
Sir can we assume the length of spreading code???
Sir can u pls upload the video for multiple access techniques?? Pls
Sir please explain me about features of pseudo noise codes
Sir I hv one doubt that where XNOR is connected in block diagram... Bcoz u explained waveform with the help of XNOR.
Thanks sir

Tq
sir please make one video on PN squence generator
is it xor /xnor cause in my course it says its xor
Processing gain of dsss is Tc/Tb (chip rate/bit rate ), if we increase chip rate then the bandwidth is increase..
what Barker code and where the placed use and how can calculate
pls.prepare these topic
Sir material on mobile radio propagation small scale fading and multipath channels
Sir I am confued as somewhere X-OR is done and you have done X-Nor.
How you are claiming that DSSS is better immune to jamming than FHSS? It’s much easier to jammed B.W separated in DSSS, while in FHSS it’s hoping in different channel at different times. If jammer is sending noise on one channel only specific chunk of data would required to retransmit in FHSS. Thank you though for working presentation of DSSS. Keep it up
Please provide an example of DSSS with interference and noise

2023.08.24 감사합니다.
Fine
Your welcome 🙏
Satellite ka video banaiye sir
please upload bicep of signal space set
actually using XOR is correct but XNOR is wrong according to gpt??
is the original signal analog or digital?
fariq burhan digital he said in starting
for analog FHSS is used
How come at 10:10 you told output code is Ex-OR and then at 10:59 it became Ex-NOR?
There is not x- Or bro kuki xor me 0 or 1 ka xor 1 hoga bt xnor me hi sirf zero hoga so sir by mistakes bol diye. Hope u got it
This is deep don't no if I fully got
Sir can u explain convolution code for (3,1,2) encoder
Noted ✅
@@EngineeringFunda thank you sir
Sir can we draw the same diagrams in exam as well??
Why not
sir add videos for gold codes,walsh code,and pn sequence
What is fhtdma?
Sir jis paper pr aap likhte uski pdf bna kr bhi share kr diya kro plzzzz
Sir abhi or course baki h aktu ka
Why we are going to spread spectrum method??
To increase data rate and to optimize bandwidth usage
Sir in DSSS is used in CDMA but in CDMA we use X-OR operation but here we use X-NOR...
Waveforms r not shown wrt psk…confused….
is it ok for 12marks
how 1 1 is become 1 and 0 0 also become 1 how sir. some thing wrong u said sir
Here...XOR- ing has some mistakes ..i think....
It is XNOR , it is not XOR
Engineering Funda ...i studied it as XOR...soo a doubt!
He first said XORing...then he rectified and said XNORing
It will be XOR✌🏻
10:42 xoring 1 and 1 is 1??🤔🤔🤔
pn sequence code genrar pls sir
how 1 xor 1 = 1 ??
Sir dsss uses xor not xnor
1 XOR 0 = 1 .Not 0 .
Xor gate output is wrong
XNOR hai bhai, sir made a slight mistake
Waste po ra bai
It is not xnor it's multiplication
It is XNOR bro.... The multiplication of 0 and 1 is 0
Pronunciation is not good
very bad explanation like reading book
people like you wake up everyday and hate on people for doing their job. The specimen of people like you are lovely to watch. Little do you know he doesn't care about comments like these, please go get a life brother. Good day
