2020 Electrical Contest Question E-Amplifier Nonlinear Distortion Research Device (Nanjing University)

Outstanding works of e-sports competition in 2020

Overview

This design implements an amplifier nonlinear distortion research device. The device can amplify the original sinusoidal input waveform by more than 100 times without obvious distortion. By adjusting the analog switch, it can achieve top distortion, bottom distortion, two-way distortion and crossover distortion, and display the total harmonic distortion of the above five waveforms. approximate value. Various waveforms are used to complete function switching and parameter control through the microcontroller combined with the touch screen. The system has a friendly human-machine interface, stable operation, and all indicators meet and exceed the question requirements.
