Abstract: PROBLEM TO BE SOLVED: To make a frequency characteristics, a phase characteristics and a distortion characteristics, to be superior without the increase of noise by switching and selecting the feed back quantity of negative feedback circuits with the gains of respective power amplifiers so as to have the same amplification level in the case of bridge connection for stereo reproduction and monophonic reproduction. SOLUTION: The outputs of right and left power amplifiers 3 and 4 are negatively fed back to the respective inversion terminal (-) inputs of the right/ left power amplifier 3 and 4 through NFB circuits 6 and 7 making negative feedback of +6dB and the ON terminals of SWa and SWb of BRIDGE SW. At the time of bridge connection for stereo reproduction and monophonic reproduction, each total gain of the right/left power amplifiers 3 and 4 becomes +6dB which is twice respectively compared with non-bridge connection. Since the negative feedback quantities of the NFB circuits 6 and 7 are set to +6dB, the gains of the right/left power amplifiers 3 and 4 become 1/2 and the total gain does not change. Then, distortion characteristics becomes superior.

Filed: 1996-12-26
Abstract: PROBLEM TO BE SOLVED: To surely collate 1st and 2nd images in simple configuration by switching the sampling pitch of 1st or 2nd image corresponding to the 1st or 2nd image. SOLUTION: A system control circuit 3 judges whether the number of segments in a valid area is less than a prescribed value or not.
