Abstract
Provided is a fast Fourier transform device for analyzing specific frequency components of an input signal. The fast Fourier transform device includes an address generator that generates an address, based on a first frequency index corresponding to a first frequency, an FFT coefficient table that outputs a first Fourier transform coefficient corresponding to the generated address among Fourier transform coefficients of the first frequency index, and an operator that calculates a frequency characteristic of an input signal associated with the first frequency, based on the input signal and the first Fourier transform coefficient.
