As the figure 14-35 shows, the generator circuit is composed of one piece of 555 and a four-D trigger. The astable multivibrator is composed of the 555 and RP1, R2, C1, the oscillation frequency f=1.44/(RP1+2R2)C1, the frequency can be changed by adjusting the RP1. The trigger D can be used as the frequency divider, S2，S3，S4 and S5 produce the 1/2，1/4，1/8 and 1/16 frequency divisions of the fundamental frequency, so we get four octave tones.
