Abstract

PURPOSE:To enable to reduce the production of operation error remarkably, with lower order of digital filters, by the series connection between a definite impulse response digital filter and an infinite impulse response digital filter. CONSTITUTION:An input signal incoming to an input terminal 2 is applied to a low-pass filter 1 consisting of series connection of a definite impulse response (FIR) digital filter 3 and an infinite impulse response (IIR) 4. The FIR digital filter 3 has an amplitude characteristic canceling a peak around the roll off frequency of the amplitude characteristics of the IIR digital filter 4 and the IIR digital filter 4 has a straight line phase characteristic at pass band.
