Square Wave and Sawtooth Wave Oscillation Circuit Design
The figure shows square wave and sawtooth wave oscillation circuits.
The circuit uses the function generator XR-2206 to form the desired oscillator. The integrated circuit can produce high-quality sine wave, square wave, sawtooth wave and pulse wave. This circuit uses it to generate square wave and sawtooth wave. The output frequency is determined by R1, R2 and capacitor C. Its oscillation frequency calculation formula is:
.
The duty cycle D of the waveform can be adjusted from l% to 99%. Its calculation formula is:
D=R1/(R1 R2)
The resistance of R1 and R2 must be in the range of 1kΩ to 2MΩ.
