Web2. The DCT for a signal x ( t) on [ 0, T] is roughly the same as the DFT for the function x ( t ) on [ − T, T], that is, mirrored at the vertical axis. Since that function is even, all sine coefficients will be zero and can be removed from the result. Now sin ( t ) is different from sin ( t) = − sin ( − t) for negative t, so the ...

WebJun 11, 2014 · Not necesarily. If it is, then it is properly called gaussian white noise. In the frequency/Fourier spectrum, how does white noise look like ? Ideally, over an infinite time interval, it will look as a flat line, because, by definition, it has the same spectral energy at every frequency. And the same with the histogram, how does it look ? Webthe DFT spectrum is periodic with period N (which is expected, since the DTFT spectrum is periodic as well, but with period 2π). Example: DFT of a rectangular pulse: x(n) = ˆ 1, 0 ≤n ≤(N −1), 0, otherwise. X(k) = NX−1 n=0 e−j2πkn N = Nδ(k) =⇒ the rectangular pulse is “interpreted” by the DFT as a spectral line at frequency ... order copy of my birth certificate
