Abstract
Modern filter design is based on the accurate selection of an appropriate input/output relationship which will satisfy the required specification of the filter. The steps involved in any successful filter design may be summarised as follows:
-
(a)
Specification of a suitable filter characteristic — for example, attenuation, phase shift, size, weight etc.
-
(b)
Selection of an appropriate rational function necessary to realise the specification.
-
(c)
Analysis of the selected circuit (equivalent to the required transfer function) and the calculation of the component values of the chosen filter circuit.
-
(d)
Preliminary computer analysis of the design using SPICE or any CAD (Computer Aided Design) package, followed by
-
(e)
the construction and testing of the chosen circuit.
