Hi, I'm using MATLAB for demodulating an amplitude modulated signal. I am using a synchronous demodulator: I multiply the signal by exp(j*wc*t) in phase with the signal and then I apply a low-pass. BEFORE being demodulated, the signal passes by a transfer function (using lsim from control toolbox). My question: Can I translate this transfer function, putting it AFTER the demodulation? How can I calculate my new transfer function? thanks in advance, Alex |
