Abstract

PURPOSE:To modulate an AM stereoscopic signal with a simple constitution by detecting the envelope and the phase of an AM stereoscopic signal, operating the tangent of the phase and multiplying the envelope by it. CONSTITUTION:For an AM stereoscopic signal e (t), an envelope is detected by a detecting circuit 21. An e (t) is inputted into an amplitude control circuit 22, an envelope component (sum signal component) is eliminated, the phase is detected at a detecting circuit 23, a detecting input is inputted into a function circuit 24, and the tangent of the phase is operated. A multiplication circuit 8 multiplies the envelope from a circuit 21 by the tangent from a circuit 24, and generates and inputs a difference signal {L (t)-R (t)}. The output of the circuit 21 and the output of the circuit 8 are inputted into a matrix circuit 11, and synthesized, and a left signal {1+2L (t)} is outputted from an addition circuit and a right signal {1+2R (t)} is outputted from a subtraction circuit 10.
