Claim 4:
5. The method of claim 1, comprising:
a) updating the weighting factor thereby updating the error function;
b) applying the least squares method using the error function to determine an alternative expression for the filter transfer function that either:
i) reduces the error function to a sufficiently small value that is indicative of the filter transfer function being sufficiently close to the target transfer function; and/or
ii) minimizes the error function;

c) updating the filter expression to the alternative expression if the error function after updating is smaller than the error function prior to updating; and;
d) repeating the steps a) to c) until:
a number of repetitions of the steps a) to c) exceed a limit; and/or
the error function is less than a threshold value.
