ABSTRACT:
Single sideband modulation system. A first single sideband of radio frequency is generated with first audio modulation on the lower side of an assigned frequency, the first single sideband bandwidth being equal to the highest frequency of said first audio modulation. A second single sideband of radio frequency is generated with second audio modulation on the upper side of the assigned frequency, the second single sideband bandwidth being equal to the highest frequency of said second audio modulation. A first stereo channel is modulated on the lower sideband frequency. A second stereo channel is modulated on the upper sideband frequency. The stereo channels are combined whereby a receiver tuned to the assigned non-transmitted carrier frequency will receive both stereo channels.
