dsp - Perform the Power Spectral Density of the signal x

Calling Sequence

[D]=dsp(x)

Parameters

Description

Perform the Power Spectral Density of the signal x.

Examples

  x=sin(0:0.01:2*%pi);
  [D]=dsp(x);
  scf;
  subplot(2,1,1);plot(x);xtitle('x');
  lx=length(D);
  if (modulo(lx,2)==1)
  ind=-int(lx/2):int(lx/2);
  else
  ind=-int(lx/2):int(lx/2)-1;
  end
  subplot(2,1,2);plot2d(ind,D);xtitle('Power Spectral Density');
