The density of a uniformly distributed random quantity X is deﬁned to be a positive constant within a certain interval, say [c, d], and zero outside this interval. 9), fX (x) = (d − c)−1 for c ≤ x ≤ d; 0 elsewhere.

Thus we can approximate the integrals involved in calculation of the Fourier transforms in the same way as one does in numerical integration in calculus, using left-handed rectangles, trapezoids, Simpson’s rule, etc. We use the simplest approximation, which is equivalent to assuming that the signal is constant between the times at which we sample (and rectangular approximations of the area under the function). Therefore, suppose that the sampling period is Ts , with the sampling frequency fs = T1s , so that the signal’s sample is given in the form of a sequence xk = x(kTs ), k = 0, 1, 2, .
