Abstract
A receiver for demodulating a stereophonic broadcast signal. Envelope detection is provided for a preselected radio frequency broadcast signal. Angle demodulation of a difference signal contained in the broadcast signal is provided at the radio frequency level avoiding the use of superheterodyne techniques. Improved linearity is achieved over detection techniques which operate at an intermediate frequency level. Receiver protection from excessive negative modulation peaks is provided as well as subsequent audio signal processing.
