Abstract:
1. A method of transmitting discrete first and second stereo channel signals from a signal source to a receiver for broadcast as first and second stereo channels, the method comprising the steps of: forming a sum signal of the first and second stereo channel signals; forming a difference signal of the first and second stereo channel signals; developing a first stereo channel signal and a second stereo channel signal from the sum and difference signals; modulating the first stereo channel signal on a first carrier frequency signal; modulating the second stereo channel signal on a second carrier frequency signal; modulating the sum signal on a third carrier frequency signal; combining the first, second and sum modulated signals and the first, second and third carrier frequency signals to form a composite modulated carrier signal; transmitting the composite modulated carrier signal; receiving the composite modulated carrier signal; and separating the first and second stereo channel signals from the composite modulated carrier signal.
