The Discrete Fourier Transform,esign of a processing system to give the desired output. There are several different mathematical tools for carrying out these two tasks. A time-domain approach was presented in Chapter 1, where a sampled input signal was represented by a weighted unit-impulse train and a DSP system was described by

Digital Filters,n. It was explained that the in-band unwanted signal at 3 kHz should be removed (filtered out) to produce the wanted signal at 1 kHz. It will therefore be appreciated that a digital filter may be regarded as a DSP system that selectively modifies the frequency components of a signal according to spe

z-Transforms,ing the s-plane representation to analyse a sampled signal or sampled-data system due to their characteristic infinite number of complementary frequency spectra. Let us consider a sinusoidal signal cosω .t which, using Euler’s identity (e. = cosθ ± jsinθ), can be expressed as
