Abstract

Disclosed is a frequency-selectable signal generator in which a numeric datum is parallel-transferred to a full adder circuit repeatedly under the control of clock pulse signals, thereby outputting an overflow signal, which is a precise division of accumulation of repeatedly inputting numbers. The frequency of the overflow signal varies with the number represented by the numeric datum. The output signal has a regular pulse-to-pulse interval, and therefore it can be used in producing a musical note.
