anaask

Purpose

Amplitude Shift Keyed (ASK) signal.

Synopsis

[y,am] = anaask(N)
[y,am] = anaask(N,ncomp)
[y,am] = anaask(N,ncomp,f0)

Description

anaask returns a complex amplitude modulated signal of normalized frequency f0, with a uniformly distributed random amplitude. Such signal is only 'quasi'-analytic.

Name	Description	Default value
N	number of points
ncomp	number of points of each component	N/5
f0	normalized frequency	0.25
y	signal
am	resulting amplitude modulation

Example

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