Narrow-band FIR filter sets

摘要

Filter sets based on narrow band-pass finite impulse response filters are introduced. The presented filter sets consist of inner and lateral filters. The inner filters are equiripple narrow band-pass finite impulse response filters based on isoextremal polynomials. They are complemented by the lateral narrow low-pass and high-pass finite impulse response filters. The filter sets presented here enable the perfect decomposition of the input signal.
