The voltage-controlled sinusoidal oscillator circuit is shown in the chart. It is composed of MC1046B. When the controlling input voltage is 0 ~ 5V, the outputcan get the sine signal withfrequencyfrom 0 ~ 20kHz.The frequency range is decided by the resistor R1 and capacitor C, changing the resistors and capacitorscould change the oscillation frequency. If the external resistor R2 connects topin 12 , oscillation frequency range could be changed. If you choose R2 = 2R1, the oscillation frequency becomes 10 ~ 30kHz.
