Wave digital filters which are derived by previously known methods from LC ladder reference filters having attenuation poles at frequencies other than zero or infinity, although being canonic in number of multipliers, are not canonic in number of delays. A simple procedure is given by means of which a canonic realization can always be derived from an originally noncanonic ladder wave digital low‐pass, high‐pass, or band‐pass filter. This procedure does not affect the values of the multiplier coefficients.
