We showed that by choosing ... where ˚(f) is an odd function if the signal x(t) is real, i.e. ˚(f)=−˚(−f). We will deal with the phase component in a more precise manner later, when we design practical lters. f X(f) −3 −2 −1 1 2 3 Webwe want to process a real signal, such as a series of voltage measurements taken over time. This group of data becomes the real part of the time domain signal, while the imaginary part is composed of zeros. Second, the real Fourier transform only deals with positive frequencies. That is, the frequency domain index, k, only runs from 0 to N /2. In
