fmconst

Signal with constant frequency modulation.

Calling Sequence

[Y,IFLAW] = fmconst(N,FNORM,T0)

Parameters

N :

number of points.

FNORM :

normalised frequency. (default: 0.25)

T0 :

time center. (default: round(N/2))

Y :

signal.

IFLAW :

instantaneous frequency law (optional).

Description

fmconst generates a frequency modulation with a constant frequency fnorm. The phase of this modulation is such that y(t0)=1.

Examples

z=amgauss(128,50,30).*fmconst(128,0.05,50); plot(real(z));
