Frequency Shift Keying (FSK) signal
[Y,IFLAW] = ANAFSK(N, NCOMP, NBF)
a positive integer: the signal length.
number of points of each component (default: N/5)
a positive integer: the number of distinct frequencies (default: 4).
a complex column vector of length N: the signal
a real column vector of length N: the resulting instantaneous frequency.
simulates a phase coherent Frequency Shift Keying (FSK) signal. This signal is a succession of complex sinusoids of NCOMP points each and with a normalized frequency uniformly chosen between NBF distinct values between 0.0 and 0.5. Such signal is only 'quasi'-analytic.
