Filter Order – The order of a discrete-time filter is the highest discrete-time delay used in the input-output equation of the filter. For Example, in Equations (4.6 or 4.7) the filter order is the larger of the values of N or M. For continuous-time filters the filter order is the order of the highest differential term used in

Discrete Time Signals Fundamentally, a discrete-time signal is sequence of samples, written x[n] where n is an integer over some (possibly in nite) interval. Often, at least conceptually, samples of a continuous time signal x[n] = x(nT) where n is an integer, and T is the sampling period. n-4 -2 0 2 4 x[n]

3.2. DISCRETE FOURIER TRANSFORMS The discrete Fourier transform (DFT) estimates the Fourier transform of a function from a flnite number of its sampled points. The sampled points are supposed to be typical of what the signal looks like at all other times. The DFT has symmetry properties almost exactly the same as the continuous Fourier transform.
