I am using Matlab Simulink to analyse Amplitude Modulation in Noise. I attached my system below.
1)In the mixer I am using a bandpass filter and another one after the envelope detector and I need to determine the minimum and maximum frequencies allowed depending on these parameters( I attached screenshots too) since I tried using mathwork site but it was not helpful regarding these values.
2)Also I need to know what needs to be changed in the model if the AM channel has a different carrier frequency.
3)What does 999e3 evaluate to?
Thanks a lot!
