Filter Types

  • Allan Waters
Part of the Macmillan New Electronics Series book series


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:
  1. (a)

    Specification of a suitable filter characteristic — for example, attenuation, phase shift, size, weight etc.

  2. (b)

    Selection of an appropriate rational function necessary to realise the specification.

  3. (c)

    Analysis of the selected circuit (equivalent to the required transfer function) and the calculation of the component values of the chosen filter circuit.

  4. (d)

    Preliminary computer analysis of the design using SPICE or any CAD (Computer Aided Design) package, followed by

  5. (e)

    the construction and testing of the chosen circuit.
