Frequency Shift Keying (FSK) signal.
[Y,IFLAW]=ANAFSK(N,NCOMP,NBF)
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.
