Name: m10 - The Discrete Fourier Transform
ID: m13881
Language: English (en)
Summary: The Discrete Fourier Transform (DFT) maps a length-N number sequence or signal into a length-N frequency domain complex number sequence which is the transform of the signal. This is a fundamental operation in computational DSP.
