Test limiar multipoint and compares with methods Sobel founded.

说明：  非平稳信号的一些处理函数，包括计算瞬时频率和群延迟及非平稳信号的生成。(Some non-stationary signal processing functions, including the calculation of the instantaneous frequency and group delay and non-stationary signal generation.)

it is a emotion detector code

经典窄带信号含有两个干扰源，最后绘制方向图(Classic narrowband signal contains two sources of interference, the pattern drawn last)

信号的时移 y(t) = x(t - t0) 其中，t0为位移量。若t0为正数，则y(t)等于将x(t)右移t0秒之后的结果(This program is used to implement the time-shift operation )
