As shown in the figure ab is the voltage controlled sinusoidal oscillator circuit composed of MC1046B . When the control input voltage is 0 ~ 5V, the output can be sine wave signals with a frequency of 0 ~ 20kHz. The frequency range is determined by resistance R1 and capacitance C, so changes in resistance and capacitance can bring about alteration in oscillation frequency. If you connect resistance R2 outside the feet12 ,you can change the oscillation frequency range. If R2 = 2R1, then the oscillation frequency will be 10 ~ 30kHz.
