Abstract
A time generator circuit comprises a reference signal generator and frequency divider circuits to divide the reference signal to generate a first signal at an audio frequency, an hour signal, and a plurality of third signals of different predetermined frequencies. The third signals are applied to a selecting circuit which selects one of these signals. An output generating circuit receives the first signal as an output time signal in response to the second signal during a time period determined by the selected one of the third signals.
