The function generator using 8038 is shown in the chart. The function generator using integrated circuit chip 8038 can get square, triangle wave and sine wave simultaneously. Triangular wave is directly formed by discharging from the constant capacitor; square wave received by the controlling signal; sine wave received by the triangular wave passing the approximation circuit. The sine curve obtained like this is not a smooth sine curve, and the distortion is about 1% and it can meet the needs of general purpose. The potentiometer PR1 in the circuit is used to adjust the frequency, its range is in 20Hz to 20kHz. PR2 is used to adjust the waveform distortion, PR3 is used to adjust the duty cycle of the waveform.
