Abstract
A timing signal generating circuit including a clock source which generates clock pulses of a predetermined period, a binary counter which divides the frequency of the clock pulses from the clock source by n, a logical array which decodes an output of the binary counter and which is composed of semiconductor elements and flip-flop circuits which are set or reset by outputs of the logical array in response to the clock pulses from the clock source with the outputs of the flip-flop circuits being used as timing signals.
