[@aaronkwizera8845]

you are best lecturer ever see. keep working hard, we appreciate u sir!!! stay blessed u are loved sir

[@EngineeringFunda]

When you write this..... it gives lot of motivation to me.

[@dakshjain7]

everything was excellent .. but sir the fact that you used m(t) and you put mx(t) was confusing for people watching this in series .

[@skinnythanos6875]

because A(c) is taken in common?

[@akankshagurjar5141]

Here m is modulation index and x(t) is msg signal

[@xiaonan238]

Thank you very much for your nice explanation in this series.. you save me a lot of time😁😁

[@rajunagulancha770]

good explanation sir....thank you sir

[@dushyanthyadav2694]

Super sir excellently said

[@EngineeringFunda]

your welcome

[@مرتضىالمحمدي]

FIRSTLY ..THANK YOU FOR YOUR EFFORTS..sir, I have question please, all previous explanations about ( DSB-LC),What about (DSB-SC)?

[@EngineeringFunda]

You just go through my playlist you get your answer.

[@مادةالسيطرة]

very good ..........thank you so much.

[@VishalSharma-ri3ih]

Great sir.... But I think there is a correction in y(t) value that is AM signal you write :- y(t)=Ac(1+modulating_index*message signal )Sinwc(t) But I think the value of y(t) should be- Y(t)= Ac(1+modulating_index*SinWmt )SinWc(t)...... Please correct me If I am wrong

[@nitishadhiman4102]

The AM equation u're talking about is generalistic in nature... In this lecture sir has shown the demodulation using square law device... He therefore has taken the equation corresponding to the AM signal generated from the square law modulator.

[@ishanagarwal680]

nice lectures...very informative

[@marcofoschi5479]

Thanks for this video. I've a question at 8:49minute you says there is no carrier signal inside mbAc^2x(t) , this is due to the fact that omegac is not present? Thanks

[@ruman2200]

Thankyou so much sir...

[@EngineeringFunda]

Your positive comments motivates me, Thanks and welcome 🙏

[@rikmajumdar2938]

Thank you so much sir 🙏🙏❤️❤️ It is very helpful 👍

[@EngineeringFunda]

Thanks and welcome

[@parthsinha2353]

sir u explain well...however there tends to b some background noise(wind blowing) in ur videos....if possible try to get rid of tat

[@EngineeringFunda]

In New setup it is not there, I have just initiated youtube channel with these videos.

[@parthsinha2353]

Gr8

[@shankysays]

Thanks

[@mrno345]

Is there some logic behind selection of components by lpf and bpf

[@sarthaksharma9322]

Low Pass filter only selects the low frequency stuff, basically it neglects all the powers and higher terms of message and carrier signals, and band-pass filter only selects a range of frequencies.

[@kokilanagaveti7965]

Thank you sir

[@swatichauhan2106]

sir is detector circuit and demodulator circuit same ?

[@priyanshu0159]

sir in last we have found original signal that is x(t) but how its equation also contains x(t) in it??? please resolve this doubt

[@061_arsh]

Is this same as rectifier detector?

[@mohammedshaikhussain4949]

1. Explain how an amplitude modulated signal can be detected using a square law detector sir this question we acn write this answer

[@EngineeringFunda]

Yes

[@Insanelymoodie]

How do we know if term is having the information ? Like for carrier term we know x(t) will be present but what about info part ?

[@475d.saikiran4]

After lpf their is Ac^2 it is the carrier amplitude but u said that the term consist of only msg signal

[@EngineeringFunda]

Information is there in frequency, amplitude can be scaled

[@sagnikpaul2388]

Sir,why you took mbAc²x(t) as the output.Here also carrier signal is present.

[@EngineeringFunda]

There is no carrier in this

[@bharathchandra4531]

Please try to make the video as shorter as you can by not unnecessarily repeating things again and again

[@ShivanshRajSrivastavaSRS]

sir how we are recognising if the term is having information or not

[@EngineeringFunda]

Based on frequency we do that

[@sourabhpatravale8348]

Too many advertisements 😔

[@kapilgupta4674]

what is this 'm' in the final expression?

[@shankysays]

Kapil Gupta u meu modulation index Am/Ac

[@goravsharma7531]

It's not modulation index wrongly written

[@kironpaul7581]

Sir ap ads bare dalte go... Really annoying sir.. Hope u will fix it 😊

[@T.saibharadwaj]

My dear sir plz stop the ads middle of the class

[@kapilgupta4674]

plz rply fast
