Abstract
PURPOSE: To improve S/N even in case that a long delay is given to small-level signals, by outputting no needless frequency by causing a variable filter, which is controlled according to frequency components, to process delayed input signals.
CONSTITUTION: Input signals not only are delayed by delay circuit 1 but also become information signals concerning frequencies by frequency detection circuit 3 such as a frequency-voltage converter circuit. When these information signals are delayed by control signal delay circuit 4 having a delay time approximately equal to the delay time of circuit 1 and are applied to variable filter, where delay signals from circuit 1 are applied, to control the frequency characteristic of filter 2, delay signals including no needless frequency components are outputted from filter 2. Consequently, good delay signals without S/N degradation can be obtained even in case that a long delay time is given to a small-level input.
