  • Abstract
    Scaling of filter variables is central to fixed point implementation of digital filters. A simple method of scaling based on scaling constants of individual sections of a cascade digital filter is presented. The proposed method saves a lot of computational labour in the implementation of higher order digital filters. Maximal amplitude expressions of second order filter transfer functions are also presented.
