Effects of Finite Register Lengths,All practical implementations of digital signal processing algorithms have to cope with finite register lengths. These lead to impairments of the filter performance that become visible in different ways.

Analog Filters,cribing characteristics of Butterworth, Chebyshev, Cauer and Bessel filters, hints are given as to how the coefficients of these filters are calculated. This will enable the reader to perform calculations going beyond the numerical data given in the design tables in the Appendix.

Discrete-Time Systems,) is calculated by convolution of the input signal .(.) with the impulse response .(.) of the system (1.1). In the frequency domain, the spectrum of the output signal .(j.) is simply obtained by multiplication of the spectrum of the input signal .(j.) by the transfer function .(j.) (1.10). In this c

Filter Structures,c elements:.The last-mentioned function corresponds to the operation of a D flip-flop in digital systems. Triggered by the rising or falling edge of the applied clock signal, the information at the input is stored and passed to the output. This leads to the situation that we find a sample value at t

Design of IIR Filters,types. While a given frequency response is approximated in case of an IIR filter by a rational fractional transfer function of ., with poles and zeros (5.18), the FIR filter is simply characterised by zeros and a polynomial of . (5.2).
