anaask

Amplitude Shift Keying (ASK) signal

Calling Sequence

[Y,AM] = anaask(N)
[Y,AM] = anaask(N, NCOMP)
[Y,AM] = anaask(N, NCOMP, F0)

Parameters

N:

a positive integer: the signal length.

NCOMP :

number of points of each component (default: N/5)

F0:

a real scalar in [0 0.5]: then normalized frequency (default: 0.25)

Y:

a complex column vector of length N: the signal

AM:

a real column vector of length N: the resulting amplitude modulation.

Description

anaask returns a complex amplitude modulated signal of normalized frequency F0, with a uniformly distributed random amplitude. Such signal is only 'quasi'-analytic.

Examples

[signal,am] = anaask(512,64,0.05);
clf
subplot(211); plot(real(signal)); 
subplot(212); plot(am);
