摘要：

PROBLEM TO BE SOLVED: To produce a chord-generating digital signal for generating a chord from one buzzer.SOLUTION: In a first step, duty ratios of a plurality of sound source digital signals of different frequencies, a signal A (600 Hz for example) and B (500 Hz for example), are reduced (to a duty ratio of 20% for the signal A and 16.7% for the signal B, for example). In a second step after the first step, the plurality of sound source digital signals are combined to produce a chord-generating digital signal.SELECTED DRAWING: Figure 5
