This paper introduces a time domain approach for designing ladder wave digital filters (WDFs) with limited coefficient wordlengths. Simple iteration equations yield the time domain response of a ladder WDF. An optimization algorithm then facilitates the design of the WDF to meet a desired response with a specific number of bits representing the coefficients. This approach also affords realizations with frequency domain constraints
