WebMany FFT algorithms based on the CT decomposition such as radix-22, radix-23, radix-4, radix-(4+2), prime-factor as well as split-radix algorithms, have been proposed using the complex mathematical relationship to reduce the hardware complexity [2-3]. For example, in [4] one butterfly unit is WebThe Radix-2 FFT works by decomposing an N point time domain signal into N time domain signals each composed of a single point. Signal decomposition, or ‘decimation in time’ is achieved by bit reversing the indices for the array of time domain data.
