Abstract :
A matrix approach is proposed for determining the coefficients of maximally flat FIR filter transfer function expressed in terms of the cosine of multiple angles. A transformation matrix maps a functional vector, the entries of which are either 0 or 1, into the coefficient vector of the transfer function. It is shown that the transformation matrix can be generated either directly or recursively
