A novel VLSI design of radix-4 DFT in current mode

Design and Simulation of a Low-Power and High-Speed Fast Fourier Transform for Medical Image Compression

“…FFT, is used as an improved version of the traditional discrete signal processing tool (discrete Fourier transform), for medical image compression with various drop ratios. FFT is widely used in medical imaging, engineering, communication, and other fields because it transitions quickly from the T-domain to the F-domain and vice versa [1][2][3][4][5][6].…”
