摘要: A sound generation circuit for producing a dual tone which includes memory circuitry storing data controlling production of the tone, selection selecting stored in and frequency dividers an output signal having varies based on selected by circuitry. The is dividing also logic to inhibit musical note when currently tone. melody dial sections employ common elements.
