Abstract

PURPOSE:To realize reduction for both the noise and the distortion factor by mixing the output of n units of circuits featuring the different central frequencies in the same phase and then giving further mixture with the input signal in the opposite phase via the (n-1)-fold or (n+1)-fold amplifier. CONSTITUTION:For circuits 11-1n featuring transmission functions T1(s)-Tn(s), the input part is connected in common to input terminal IN with the output part connected to each inverse input terminal of mixer 2 each. At the same time, amplifier 3 featuring the amplification factor of (n-1)-fold is connected to noninverse input terminal of mixer 2 as well as to terminal IN. In this case, the amplification factor of amplifier 3 can be set also to (n+1)-fold. As a result, a sound quality adjuster featuring multiple channels can be realized.
