DIGITAL water marking

给出两个chirp信号相加后，由瞬时频率定义求出的瞬时频率曲线，说明瞬时频率的不确切性；(The sum of two chirp signals are given, after the definition of instantaneous frequency derived from the instantaneous frequency curve, indicating lack of precision in the instantaneous frequency )

一些很基础的，很有用的matlab小程序(some very basic, very useful small Matlab procedures)
