dpll源程序
- 一种设计数字锁相环的思路，包含异或鉴相器、k模可逆计数器、脉冲加减计数器、N分频器等，实现相位的锁定。(A design of digital phase locked loop (PLL) consists of a phase discriminator, a K mode reversible counter, a pulse addition and subtraction counter, a N frequency divider and so on, to lock the pha

- 基于整数小波变换的图像可逆水印，很好用，可逆性很强，自己查找的资料(Image reversible watermarking based on integer wavelet transform is very useful. It has strong reversibility and finds information by itself.)
正反转可控的直流电机
- 单片机应用实例，实现正反转可控的直流电机(Single chip microcomputer application example to realize direct and reversible DC motor.)
可逆素数
- 输入一个数判断该数是否是一个可逆素数，如果是输出**是可逆素数，否则为不是！(Enter a number to determine if the number is a reversible prime number. If it is output * is a reversible prime number, otherwise it is not!)
St_filter
- S变换时频域滤波是一种二维的时间域—频率域的分析方法，此程序通过对信号进行时频域转换，通过分析干扰信号的时间与频率的分布范围，设计相应的滤波器进行滤波可以有效的去除干扰，又因为S变换的是无损的可逆的因此对信号没有损伤。(S transform time domain filtering is a two-dimensional time domain - frequency domain analysis method. By analyzing the time and frequency d
