Inverse Discrete Fourier Transform of a finite sequence The Fourier transform takes a signal in the time domain and maps it, without loss of information, into the frequency domain. The frequency domain representation is exactly the same signal, in a different form. The inverse Fourier transform(IDFT) maps the signal back from the frequency domain into...

Zoom Spectrum This function returns N point DFT samples of 2dw band of Fourier transform of a sequence. Typically, fft() returns N samples of Fourier transform ranging from 0 to 2pi. This function takes the N-point DFT samples and returns N-point samples corresponding to frequency band wc-dw to wc+dw.
