a system and method for implementing a digital filter , comprising computing on a digital computer a mathematical model of a digital filter ; where the mathematical model has a predetermined first set of parameters . the first set of parameters is converted to a second set of parameters , where the second set of parameters includes control parameters for a pre - selected digital - filter integrated circuit . the system then verifies that the execution of the second set of parameters by the digital - filter ic substantially reproduces the behavior of the mathematical model . the verified second set of parameters is then written to permanent storage on the digital - filter ic . the system preferably reads a device - file map characteristic of the particular filter ic intended to be used to implement the filter under design . the converting of the first set of parameters to a second set of parameters further includes computing values corresponding to the second set of parameters that conform to the numerical precision available in the digital - filter ic , and assigning the values so computed to the second set of parameters . the mathematical model of the digital filter is verified by re - computing the model using the second set of parameters .
