Abstract :
An amplitude modulated stereophonic system, which is compatible with conventional monophonic AM systems, is presented in this paper. First, conditions on the envelope and phase function for the transmitted signal are derived. Then, a compatible quadrature AM(compatible QUAM) system is proposed for the transmission and reception of stereophonic program material. Some results of testing the proposed system are included.
