Continuous-Time Systems,e systems. For a certain class of systems which have the properties of linearity and time-invariance (LTI systems), this theory provides relatively simple mathematical relationships. In the present textbook, we restrict ourselves to the consideration of filters which possess these two properties.

Analog Filters,sign of digital filters with related characteristics. For each of these types, the equations are derived to determine filter coefficients which meet the tolerance scheme of a desired frequency response. Some tables of filter coefficients can be found in the appendix which allow the filter design for

Discrete-Time Systems, numbers. Having in mind a physical meaning behind a discrete-time signal, the physical quantity can always be recovered by multiplying the numbers of the sequence by a reference value of this quantity. This is exactly what digital-to-analog converters do. In the following, the input sequence of the

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 (5.30), the FIR filter is simply characterised by zeros and a polynomial of . (5.2).
