[@ishmart8278]

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)

[@304shahidbashir8]

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

[@jayantkumbhar8049]

Nice Explanation. One question: What is the difference between synchronous detection and coherent detection?

[@aumdave1607]

Both are same

Sir, how we will prove that...AM signal is recovered , irrespective of the percentage modulation by using this (synchronous detector)

Thank u sir

[@ujjwaldasyadavladania9962]

Sir is coherent and synchronous detection are same??

[@rahuldinkar6845]

Is it the same topic as the demodulation of dsbsc

[@R4W_Pallavi]

Sir thanku for your videos I have a doubt sir how I will get to know that the signal is unwanted?

[@EngineeringFunda]

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

[@R4W_Pallavi]

Thanku sir

[@mademguruchakravardhanredd5616]

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..

[@nithishswarareddy5186]

explain the topic superheterodyne receiver sir

[@EngineeringFunda]

It is there in Analog communication playlist

[@ethanhu2831]

Quick comment: synchronous detection (or demod) is same as coherent detection (demod)!

[@EngineeringFunda]

Synchronous means coherent

[@vaibhavlakhchoura3555]

Can we take carrier signal as sine wave

[@EngineeringFunda]

Yes no issues with that

[@vaibhavlakhchoura3555]

In this case too na

[@EngineeringFunda]

😀 yes

[@VishnuVardhan-iz4he]

In that case, 2sinAsinB=cos(A-B)-cos(A+B)

[@feelmusical8731]

Sir please explain the topic CARRIER RE-INSERTION METHOD OF DETECTION IN DSB-SC...

[@shankysays]

Sir, please make video on costas loop and quadrature carrier multiplexing.

[@kapilgupta4674]

The expression for output of low pass filter in that is it Ac or Ac^2? plz rply fast

[@EngineeringFunda]

It is AM only.

[@kudumulakondamma8905]

Synchronous detector and coherent detector are same or not sir

[@EngineeringFunda]

Same

[@kudumulakondamma8905]

@@EngineeringFunda thank u sir for clearing my doubt

[@ravichandranavalgund2679]

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

[@EngineeringFunda]

It doesn't make any difference

[@IntroAct3350]

Warbling effect in dsbsc

[@bilashdutta7065]

plz upload pcm and dm video

[@EngineeringFunda]

Next month I will upload complete digital communication lecture series

[@madhurimadas9635]

Synchronous detection and coherent detection aren't same? In book it's written they are same. Please clear my doubt.

[@EngineeringFunda]

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.

[@rahuldinkar6845]

Hey madhurima i have some doubts can you help me

[@Maadhuri3]

Tqqqqqqqq sooooo much sir Your videos are like "water found in desert"

[@AshishKumar-qe4hq]

[@EngineeringFunda]

With phase lock loop we do that.

[@EngineeringFunda]

Yes

[@rudranshgoyal1832]

What is frequency error here

[@nagav261]

we r giving the s(t) as a input to the product modulator but written wrong there bro

[@rahulvishwakarma5868]

constant phase error how solved

[@subhabratamukherjee6453]

Same question, how is it solved

[@vaibhavlakhchoura3555]

In this case too na

[@litegamer8860]

sir ur explanation is very confusing u should have taken m(t)=Am coswmt

[@EngineeringFunda]

It doesn't matter, dear

[@void-li3tn]

​@@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.

[@void-li3tn]

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
