[@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.

[@easwarsendhil]

You are videos are time less classic which will liked by the current students and also by the future engineering students when they see your video

[@EngineeringFunda]

Your Appreciations, care and share matters a lot to me. #EnginneringLove. Let me give the details of few exciting features of Engineering Funda: 1. A link to more than 30 Courses is given in the Comment Section. 2. Detailed Syllabus of the subject along with chapters is given in the description of videos.

[@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😁😁

[@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.

[@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

[@dushyanthyadav2694]

Super sir excellently said

[@EngineeringFunda]

your welcome

[@rajunagulancha770]

good explanation sir....thank you sir

[@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.

[@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.

Thank you very much sir

[@harim8771]

Actually i felt difficulties in many topics when my sir took but after i saw this video I don't have any difficulties..sir Thank you soo muchh for the clear explanation...💯❣️

[@harim8771]

Sir can u post a video on Weaver's method sir plz

[@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.

[@swatichauhan2106]

sir is detector circuit and demodulator circuit same ?

[@ruman2200]

Thankyou so much sir...

[@061_arsh]

Is this same as rectifier detector?

[@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 ?

[@kokilanagaveti7965]

Thank you sir

[@shankysays]

Thanks

[@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

[@ShivanshRajSrivastavaSRS]

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

[@EngineeringFunda]

Based on frequency we do that

[@sagnikpaul2388]

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

[@EngineeringFunda]

There is no carrier in this

[@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

[@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

[@bharathchandra4531]

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

[@T.saibharadwaj]

My dear sir plz stop the ads middle of the class

[@kironpaul7581]

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