Electronic metronome using quartz oscillator - has tempo signal generator with flip=flops for dividing fundamental tempo signal to musical level

摘要

The electronic metronome has an oscillator for supplying a normal frequency from which a fundamental tempo signal is obtained via a tempo signal generator. A timing setting circuit using flip-flops divides the fundamental tempo signal and a delayed flip-flop circuit supplies a tempo signal with a predetermined phase delay. The outputs of the flip-flop circuits and the delayed flip-flop circuit are supplied to a gating circuit the output of which has a signal rise time corresponding to the pulse rise time of the fundamental tempo signal. The output of the gating circuit is coupled to an optical display and a loudspeaker.
