本程序是直流电机控制实验，程序采用定时中断产生PWM方波，100次中断为一个周期。-This procedure is a DC motor control experiment, procedures used interrupted from time to time have a PWM square wave, 100 times a cycle of disruption.

基于MATLAB的信号发生器设计,产生正弦波、三角波、方波、锯齿波-Based the MATLAB signal generator designed to generate sine, triangle, square, ramp ...

用python产生方波图像以及对其作傅里叶变换，通过三维图显示频谱图-Square image and Fourier transformation with python
