Permuted difference coefficient digital filters
Kenji Nakayama · 2005
A new difference coefficient FIR digital filter is proposed in this paper. Its coefficient is obtained as the difference between the successive values of the original coefficients permuted in large magnitude sequence. It is effectively applied to every kinds of filter responses. Computation complexity becomes about 18 % and 13% for 99th and 299th order FIR filters, compared with a direct FIR filter realization.
