Abstract :
A low-sensitivity realization of linear-phase FIR (finite impulse response) digital filters with a cascade structure is proposed. The zeros of the transfer function, which are off the unit circle in the z-plane, are realized by using complex coefficient filters. The other zeros on the unit circle are realized by conventional real filters. Simulation results of a magnitude response show the efficiency of the proposed realization
