PURPOSE:To perform effectively the automatic waveform equalizing operation, by providing a converting arithmetic circuit, which subjects the output signal of an integration circuit to the converting operation in accordance with a certain algorithm to correct and output a weighting coefficient controlling signal, between the output of the integration circuit and a weighting circuit. CONSTITUTION:An input signal is inputted to a three-stage cascade connection circuit of delay circuits 1, and respective outputs of circuits 1 are sent to an adder 5 through weighting circuits 3, 2, and 4, and the output of the adder 5 is discriminated by a discriminator 6 and is outputted. The output signal of the discriminator 6 is substracted from the output of the adder 5 by an error signal detector 7, and error components are outputted. The output signal of this detector passes through a shift register 8 and is inputted to multipliers 9, 9', and 9'' and multipliers 13 and 13'. These multipliers multiply two input signals and give results to integrators 14, 10, 10', 10'', and 14', and respective outputs of integrators are inputted to a circuit 11, and in the circuit 11, five input signals S-2- -S2 are subjected to the correcting operation based on a prescribed algorithm to output three output signals. |
