I looked at the algorithm of comm.FMDemodulator, and I have a question: comm.FMDemodulator does not require the input of the carrier frequency (fc). So how does it perform the step ys(t)=Y(t)e−j2πfcty_s(t) = Y(t) e^{-j 2pi f_c t}ys​(t)=Y(t)e−j2πfc​t? Or is it using another method, such as phase demodulation?I looked at the algorithm of comm.FMDemodulator, and I have a question: comm.FMDemodulator does not require the input of the carrier frequency (fc).
