Name: The DFT, FFT, and Practical Spectral Analysis
ID: col10281
Language: English (en)
Summary: This course reviews the Discrete Fourier Transform and explains its practical use in frequency, spectral, and time-frequency analysis of signals. It gives an in-depth explanation of many Fast Fourier Transform (FFT) and FFT-based algorithms and a practical guide to their selection and use.
