The control of all the functions is accomplished by serial bus.The AC signal setting is obtained by resistor net-works and switches combined with operational amplifiers. Thanks to the used BIPOLAR/CMOS Technology,Low Distortion, Low Noise and DC stepping are obtained.obtained.LOW VOLTAGE TONE CONTROLDIGITALLY CONTROLLED AUDIO PROCESSORFigure 2.
