全面的常用数字信号调制代码

本代码是单相正弦电压锁相环程序，用于根据单相正弦电压生成其相位角度信息，包括：正交处理、坐标变换、PI运算、积分运算、取模运算等步骤。(This code is a single-phase sinusoidal voltages phase-locked loop program for generating the phase angle information based on single-phase sinusoidal voltage, comprising: an orthogonal processing, coordinate conversion, PI operation, integral operation, the modulo operation and other steps.)

说明：  边缘检测是图形图像处理、计算机视觉和机器视觉中的一个基本工具，通常用于特征提取和特征检测，旨在检测一张数字图像中有明显变化的边缘或者不连续的区域，在一维空间中，类似的操作被称作步长检测（step detection）。(Edge detection is a basic tool in graphics and image processing, computer vision and machine vision. It is usually used for feature extraction and feature detection. It aims to detect the edge or discontinuous area with obvious changes in a digital image. In one-dimensional space, similar operations are called step detection)
