Known methods for IIR digital filters design require specification of filter order. In case of direct methods applied for filters with the prescribed linear phase response, the order cannot be derived from the specified filter parameters. The authors propose a procedure for filter order estimation, based on design of the FIR filter prototype, with the same design parameters. Two examples demonstrate application of the proposed procedure for filter design tasks. Comparison of the filter order obtained by the discussed approach with the real value has been also presented.
