Work of the circuit The circuit consists of OSC A, OSC B and step-up circuit. (It is showed in picture 9-37.) OSC A is used to produce signal of low frequency to control OSC B. change the value of RP1 to change the rate of the signal of low frequency. OSC B is under the control of OSC A. It can produce pulse signal string of low frequency. The signal is amplified and changed by the step-up circuit. It produces pulse voltage of low frequency on W2-W5. The voltage is adjusted by RP2-RP5. Then it is added on the proper part of body by poles.
