Musical tone generation in a paging system is most efficiently accomplished by circuitry which can be incor- porated into an existing support IC, as opposed to the addition of a special function IC. However, in order to minimize IC space requirements and current drain such circuitry must provide sutlicient tone resolution without resorting to complex methods such as frequency syn- thesis. Fractional division of a readily available crystal oscillator clock signal is the most efficient approach.
