ABSTRACT:
A multichannel FM subcarrier broadcast system is disclosed which enables the transmission of multiple independent signals by generating independent sidebands of suppressed carriers in the subcarrier band of an FM transmitting station. Transmitting and receiving apparatus is disclosed which employs phase shift networks to minimize interchannel distortion, thus allowing close spacing of adjacent sidebands.
