Short‐Time Fourier Analysis

  title={Short‐Time Fourier Analysis},
  author={Alfred Mertins},
In an effort to correct this deficiency, Dennis Gabor (1946) adapted the Fourier transform to analyze only a small section of the signal at a time-a technique called windowing the signal. Gabor's adaptation, called the Short-Time Fourier Transform (STFT), maps a signal into a two-dimensional function of time and frequency. The STFT represents a sort of compromise between the time-and frequency-based views of a signal. It provides some information about both when and at what frequencies a signal… CONTINUE READING
