Abstract

PURPOSE:To form a circuit free from variation in output level by providing a negative feedback system from the output to the input by connecting the output of parallel-connected circuits via a resistance that prevents termination of impedance due to an accident. CONSTITUTION:Input impedance values 91 and 101 of parallel-connected circuits 9 and 10 are set more than ten times as high as input impedance 31 of the circuit system and output impedance values 92 and 102 are set less one tenth output impedance 32 of the circuit system, thereby making connections via certain resistances 13 and 14. Further, the negative feedback system is provided which includes hybrid branch circuit 34 and negative feedback circuit 4 from outputs of circuits 9 and 10, so that level variation due to variation in load impedance of a circuit having run into trouble will be reduced to one over a feedback difference.
