Cofificador stereo multiplex (MPX) FM transmission.

摘要

multiplex stereo encoder for FM transmission with a digital signal processor, characterized in that for stereo transmission modulation vestigial sideband is applied instead of the modulation double sideband usual and that the tuning frequency of sampling is performed at the double modulation frequency, which can use the smoothing filter DAC that generates the modulated signal of the vestigial sideband.
