Abstract
PURPOSE: To make it possible to vary delay time freely, by providing a control oscillator which provides external variation in oscillation frequency, a counter for a decrease in oscillation frequency, and a switch circuit which controls this counter.
CONSTITUTION: Applying input signal (i1) to set-reset type FF6 sets FF6, and then pulses of a frequency set by voltage setter 1, generated by voltage control oscillator 2, appear at the output of AND circuit 3. On receiving a signal from output Q' of FF6, differentiating circuit 7 outputs differential outputs of a high level to set n- scale counter 4, thereby starting to count output pulses of circuit 3. When the counter is reset by counting an n-th pulse, differentiating circuit 5 is held at a high level to output signal O1 with delay time T from signal (i1). Simultaneously, FF6 is reset, stopping counter 4. Therefore, varying the set value of setter 1 varies a frequency freely, so that any delay time can be obtained.
