Patent abstract
A stereo multiplex encoder (MPX) for FM transmission with a digital signal processor utilizes residual sideband modulation in stereo transmission instead of the conventional double sideband modulation. The adjustment of the sampling frequency to the modulation frequency (fmod=fs/2) is carried out, so that the antialiasing filter of the DAC can be used which produces the residual sideband modulated signal.
