The circular convolution, also known as cyclic convolution, of two aperiodic functions (i.e. Schwartz functions) occurs when one of them is convolved in the normal way with a periodic summation of the other function.

本课题研制了一种宽频带的数字锁相放大器，可以完成自动增益和相位 可调整，最长积分时间为100s，适合于频率从10Hz到10kHz，幅值从100nV 到10mV的微弱正弦信号检测。测量结果表明，当采样点数N大于8192时， (This project developed a wideband digital lock-in amplifier, can be completed automatically adjustable gain and phase, the longest integration time of 100s, suitable for the frequency range from 10Hz to 10kHz, amplitude from 100nV to 10mV of weak sine signal detection. The measurement results show that, when the sampling point number N is greater than 8192 hours,)

文件为关于如何用matlab进行编程的资料，用matlab编程比用C语言更容易，它的矩阵运算能力更是c语言难以比拟的。再用matlab编程时，一些小细节忘了可以看一下此文件。(Document on how to use matlab to program information with the matlab programming language more easily than C, its capacity is c matrix operations can not match the language. Then matlab programming, forgot some small details can look at this file.)

王丰华等提出的相位差分法的实现，主要用于信号处理中提取信号的瞬时频率。注意该方法只适用于单分量信号。另外一个是利用自相关法求瞬时频率(Wang Fenghua such as the phase difference method to achieve, mainly used for signal processing to extract the instantaneous frequency of the signal. Note that this method is only applicable to single-component signal)
