    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

  • @مرتضىالمحمدي

  • @VishalSharma-ri3ih
    @VishalSharma-ri3ih 3 ปีที่แล้ว +2

    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
      @nitishadhiman4102 3 ปีที่แล้ว +1

      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.

  • @mrno345
    @mrno345 5 ปีที่แล้ว +2

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

    • @sarthaksharma9322
      @sarthaksharma9322 5 ปีที่แล้ว +1

      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.

  • @061_arsh
    @061_arsh 5 หลายเดือนก่อน

    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
    @475d.saikiran4 3 ปีที่แล้ว

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

    • @EngineeringFunda
      @EngineeringFunda  3 ปีที่แล้ว

      Information is there in frequency, amplitude can be scaled
