Digital signals discrete Fourier transform

In both scientific computation and digital signal processing, one must use the discrete Fourier transform (DFT), which is applied to a discrete complex valued series instead of continuous domains. The forward DFT is defined as... [Pg.352]

As will be evident in the foUowing subsections, a number of radar signal processing functions are implemented via the fast fourier, transform. The FFT is a computationally efficient implementation of a discrete Fourier transform. A number of high-throughput digital engines possess optimized hardware/software to perform FFTs. [Pg.1836]
