Function File: y = ssbmod (x, fc, fs)
Function File: y = ssbmod (x, fc, fs, phi)
Function File: y = ssbmod (x, fc, fs, phi, band)

Creates the SSB modulation of the amplitude signal x with carrier frequency fc , sampling frequency fs initial phase : phi and specified band : band initial phase : phi and specified band : band are optional arguments and initial phase : phi will be considered 0 if not given. specified band : band by default is lower sideband, but upper sideband can be specified by giving ’upper’ as the fourth argument.

Inputs:

  • x: amplitude message signal
  • fc: carrier frequency
  • fs: sampling frequency
  • phi: initial phase (defaults to 0)
  • band: specified band (if upper)

Output:

  • y: The SSB modulation of x

Demonstration 1

The following code

 #carrier frequency
 fc=400;
 #sampling frequency
 fs=8000;

 t=0:(1/fs):0.1;

 #message signal y
 y=sin(20*pi*t);

 #ssb modulation
 y1=ssbmod(y,fc,fs);

 #plot results
