Discrete Fourier Transform (DFT)
home.engineering.iastate.eduDiscrete 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 discrete values of ω, •Any signal in any DSP application can be measured only in a finite number of points. A finite signal measured at N ...

sigproc.mit.eduYet Another Fourier Representation Why do we need another Fourier Representation? Fourier series represent signals as sums of sinusoids. They provide insights that are not obvious from time representations, but Fourier series only de ned for periodic signals. X[k] = X n=hNi x[n]e−j2πkn/N (summed over a period)

www.ee.iitb.ac.in1 Discrete-Time Fourier Transform (DTFT) We have seen some advantages of sampling in the last section. We showed that by choosing the sampling rate wisely, the samples will contain almost all the information about the original continuous time signal. It is very convenient to store and manipulate the samples in devices like computers.
