Analytic projection of unit amplitude impulse signal.
Y=anapulse(N) Y=anapulse(N,TI)
a positive integer value: the signal length.
a positive integer value: the time position (index) of the impulse (default : round(N/2)).
a complex column vector of length N: the signal samples.
anapulse returns an analytic N-dimensional signal whose real part is a Dirac impulse at index t=TI. The Dirac heigth is 1.
