自己编写的短时傅里叶变换（STFT）程序，短时傅里叶变换可以获得非平稳信号的时频图，主要原理是用滑窗截取一段信号，认为这一段时间内信号是平稳的，对其进行fft变换获得频谱-I have written a short time Fourier transform (STFT) program, short-time Fourier transform can be obtained non-stationary signal frequency diagram, the main principle is the interception of a signal with a sliding window that within this period of time the signal is stationary, access to spectrum fft transform them
