Generic function generator circuit

Signal generator can be divided into three parts. They are the sine wave and triangular wave generator, the counter and the pulse and ramp generator. As shown, XR2206 uses s voltage-controlled oscillator, whose frequency adjustment can be achieved by potentiometer RP5 (10k). It is easy to adjust the frequency to be within one-thousandth of the frequency or less. If you change the resistance of the fixed resistor R3, the resistance of RP5 can also be changed. Sine wave and triangular wave circuit is similar to other similar instruments. The different attenuation switch Sl only changes the amplitude of the signal, but can not affect the bias voltage.
