Short-time fourier transform

2015-05-24 05:30    By:neighbor      View:55      Download:0

The short-time fourier transform (STFT) is used for transforming a signal of time to frequency domain, but often is used when our signal has low amplitude and some ranges of frequency close. In this code you can choose what window to use. gaussian, hamming.. etc....
