Same modulation types as the modulate function. Performs FM modulation. These functions use Welch's method of power spectrum estimation to give the results of the spectrum function in smaller pieces. They plot results by default, and use a specified window, overlap rate, FFT length, sampling frequency, and detrending option. Takes an additional sampling frequency parameter Fs.
Plots log magnitude and phase in figure window if no output parameters are present.
Plots log magnitude and phase in figure window if no output parameters are present. Takes an additional sampling frequency parameter Fs. Allows you to specify a vector of frequencies instead of just a number. Plots the group delay in figure window if no output parameters are present. Filter Design remez - The remez function now works in a more general way.
