Abstract

PURPOSE:To extend the characteristic variation range to eliminate occurrence of the phase and amplitude distortion by isolating the signals through two types of filters featuring the amplitude properties approximate to the square sine and cosine properties and then varying the addition conditions of the signals. CONSTITUTION:The equalizer circuit consists of circuits 1 and 2 possessing common input terminal 10 plus circuit 4 which adds these circuits' output together. Circuit 1 features the amplitude properties which is approximated by the linear phase properties and the square cosine properties; while circuit 2 features the amplitude properties which is approximated by the linear phase properties and the square cosine properties or the low pass band filter properties respectively. Then the addition ratio of the output of circuits 1 and 2 is varied. As a result, the range of the characteristic change can be extended to eliminate occurrence of the phase and amplitude distortion.
