Abstract

PURPOSE:To change the frequency characteristics without deteriorating the signal quality through parallel connection of band pass filters. CONSTITUTION:The input of n sets of band pass filters 11-1n is commonly connected to the output of the addition circuit 5, and the output is respectively connected to the inversion terminal of the addition and subtraction circuit 6 and also connected to the inversion terminal of the addition circuit 5, and the output of the addition circuit 5 is connected to the non-inverting terminal of the addition and sub- traction circuit 6 separately. Further, by changing the characteristics of the filters 11-1n, the audio tone can be adjusted.
