Reply To: LPF filter at receiver

[Naazira BadarParticipant]

Hi Burhan num mina llah and Hamza Ali Abbas Khan..

thankyou for replying yet again.

My query revolved the basic idea that in homodyne receivers, low pass filters are responsible for noise reduction and pulse shaping.
However, in heteroyune receiver circuits, low pass filters are responsible for suppression of unwanted demodulation products.

Here is the reference link : https://books.google.co.in/books?id=iUld6xblvo0C&pg=PA363&lpg=PA363&dq=difference+in+uses+of+lpf+in+heterodyne+and+homodyne+filters&source=bl&ots=j7gsxfR6wW&sig=UDAJYsIsonhEyGgQMCQ96KemP50&hl=en&sa=X&ved=0ahUKEwju49LrqM_MAhVLGo4KHQTxBXcQ6AEIOTAE#v=onepage&q=difference%20in%20uses%20of%20lpf%20in%20heterodyne%20and%20homodyne%20filters&f=false

I hope i am clear.

best wishes
