Active type phase equalizer

Abstract

Abstract PURPOSE:To simplify the circuit constitution by connecting a buffer output terminal to an inverting input terminal of a 1st operational amplifier, inserting two resistors connected in series between a noninverting input terminal of the operational amplifier and the output terminal of the buffer and connecting the connecting point of the resistors to the inverting input terminal on a 2nd operational amplifier. CONSTITUTION:The noninverting output terminal of the operational amplifier OP2 is connected to an input terminal of a buffer BF and connected to a noninverting input terminal of the operational amplifier OP1 via a capacitor C2. The output terminal of the buffer BF is connected to the inverting input terminal of the operational amplifier OP1 and connected also to the noninverting input terminal Of the operational amplifier OP1 via resistors R1, R2 connected in series. The connecting point between the resistors R1, R2 is connected to the inverting input terminal of the operational amplifier OP2. An output signal Y(S) is obtained from the output terminal of the buffer BF. The operational amplifiers OP1,OP2 are differential input type operational amplifiers each having one output terminal. Thus, since two operational amplifiers are enough for the tilted equalizer, the circuit is simplified.
