ABSTRACT:
An apparatus for modulating signals for use in AM stereo transmission having left and right signal inputs feeding respective inverted and non-inverted inphase modulators and respective inverted and non-inverted quadrature modulators. The inverted and non-inverted inphase outputs are summed, the inverted and non-inverted quadrature outputs are summed, and the resulting inphase and quadrature signals are summed. The resulting signal is fed to a limiter and then to a broadcast transmitter, such as a difference transmitter, as a radio frequency input.
