Abstract
PURPOSE:To make it possible to vary attenuation easily by composing a variable amplitude equalizer, equivalent to a Bode type variable amplitude equalizer, of one variable conductance and one constant resistance circuit. CONSTITUTION:Terminal 2 is grounded and terminal 1 is connected to inverted input terminal (-) of operational amplifier Q1 by way of conductance G1 and also to uninverted input terminal (+) of amplifier Q1 by way of conductance G3. The output of amplifier Q1 is fed back to inverted input terminal (-) of amplifier Q1 by way of conductance G2. Between uninverted input terminal (+) of amplifier Q1 and the earth, the parallel circuit of constant resistance circuit N1 and conductance G4 terminated by variable conductance Ga is interposed. Consequently, amplitude equalization is carried out through circuit N1, conductance G4 and variable conductance Ga.
