Amplitude Shift Keying (ASK) signal
[Y,AM] = anaask(N) [Y,AM] = anaask(N, NCOMP) [Y,AM] = anaask(N, NCOMP, F0)
a positive integer: the signal length.
number of points of each component (default: N/5)
a real scalar in [0 0.5]: then normalized frequency (default: 0.25)
a complex column vector of length N: the signal
a real column vector of length N: the resulting amplitude modulation.
anaask returns a complex amplitude modulated signal of normalized frequency F0, with a uniformly distributed random amplitude. Such signal is only 'quasi'-analytic.
