Design and Implementation of Comprehensive Experiment Based on Analog Component Waveform Generator

The integrated component——operational amplifier is designed as the core component, and the integrated comprehensive verification experiment is completed, including the same direction integration circuit, proportional operation circuit, addition and subtraction operation circuit and active filter circuit. The experiment uses four waveforms of square wave, triangle wave, rectangular wave and sine wave as the verification object, and the seven-segment digital tube is controlled by the digital dial switch to display four numbers of 1, 2, 3 and 4, and four-way waveform switching and independent output are realized by four circuits of analog signals. The characteristic of this experiment is that the design part integrates the design and debugging of the unit circuit of digital circuit and analog electronic technology, and introduces the objective evaluation standard of waveform distortion in the test part, which has good enforceability.
