Abstract

PURPOSE:To transmit accurately DC components also in a delay device using charge transfer elements. CONSTITUTION:The input signal applied to a terminal 101 is supplied to a delay circuit 102 consisting of charge transfer elements. The delay signal from the delay circuit 102 is supplied to a gain correcting circuit 104 through an adder 103, and the input signal has the gain corrected and input signal has the gain corrected and is obtained in an output terminal 105. This gain corrected signal and the input signal are supplied to a subtractor 106 to operate a difference between them. The differential output from the substractor 106 is supplied to a low pass filter 107, and low frequency components namely, DC components are taken out and are supplied to the adder 103 through an amplifier 108. That is, even if DC components are fluctuated in the delay circuit 102, they are so fed back that they have no difference between the input signal and the output signal. Consequently, a delay output where DC components are transmitted accurately is obtained in the output terminal 105.
