-17- Abstract of the Disclosure A method is described for generating continuously variable sets of weighting coefficients for application to weighting circuits of a sampled data filter. The generated coefficients are produced by scaling the time axis of the impulse response described by a set of standard or nominal weighting coefficients in an inverse manner to a desired scaling of the filter frequency response. The coefficient values at the scaled time points are calculated by a piecewise linear interpolation process and correspond to the scaled coefficients. By this technique, a large number of sets of weighting coefficients may be generated from a single set of coefficients with relatively few circuit elements.
