What is DFT and FFT in LTI Systems about?
The document discusses Fourier analysis techniques. It explains that [1] the Fourier transform represents any signal as a sum of sinusoids with different frequencies, [2] the discrete Fourier transform (DFT) calculates the coefficients for a finite number of samples, and [3] the fast Fourier transform (FFT) computes the DFT more efficiently in O(n log n) time instead of O(n2) time for the DFT. An example is provided to demonstrate calculating the amplitude and phase of a signal using the DFT.
