Dft act 1
WebDiscrete Fourier Transform (DFT) Recall the DTFT: X(ω) = X∞ n=−∞ x(n)e−jωn. DTFT is not suitable for DSP applications because •In DSP, we are able to compute the spectrum only at specific WebIn this first part of the lab, we will consider the inverse discrete Fourier transform (iDFT) and its practical implementation. As demonstrated in the lab assignment, the iDFT of the DFT of a signal x recovers the original signal x without loss of information. We begin by proving Theorem 1 that formally states this fact.
