<P>PROBLEM TO BE SOLVED: To provide a stereo demodulator circuit for maximizing a separation characteristic by matching the phases of a main channel signal and a subchannel signal. <P>SOLUTION: In this stereo demodulator circuit having a matrix circuit for generating and outputting an L signal and an R signal on the basis of the main channel signal and the subchannel signal in a stereo signal, The preceding stage of the matrix circuit is provided with a first phase adjustment circuit for adjusting the phase of the main channel signal and a second phase adjustment circuit for adjusting the phase of the subchannel signal to match the phase with the phase of an output of the first phase adjustment circuit. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
