Abstract
The design is based on the function generator ICL8038 control signal generator,waveform generator module,input module,sin gle chip converter module,the digital display module circuit.The function generator ICL8038 generates a square wave,sine wave and trian gle wave,and converted by the microcontroller AT89S52 frequency of 20 ~ 20KHz pulse waveform signal,the digital tube display.Output pulse waveform duty cycle of the sine wave distortion adjust ICL8038 can take advantage of the pin function and the external circuit cur rent or potentiometer adjustment and control.
