Hi
I would like to know if each receiver's modulation has some noise figure (NF) level associated? If yes, I would like to know what is the ASK and FSK modulation's noise figure ?
(For exemple, if receiver uses ASK modulation. Than, we can say that NF = x dB.)
thank you

There is no such definition for receivers.NF is a metric that defines how much noise power will be added onto signal while receiver is processing the incoming signal.
Different Modulation Techniques have different "immunity" against S/N ratio at the input of the demodulator. Of course S/N ratio is related to Noise Figure of the receiver so modulated incoming signal will also be related to this ratio.But There is nos such definition as you have mentioned.
