Signal with constant frequency modulation.
[Y,IFLAW] = fmconst(N,FNORM,T0)
number of points.
normalised frequency. (default: 0.25)
time center. (default: round(N/2))
signal.
instantaneous frequency law (optional).
fmconst generates a frequency modulation with a constant frequency fnorm. The phase of this modulation is such that y(t0)=1.
