Abstract

An adjustable frequency- dependent attenuation corrector circuit designed as an unblanced electrical four-terminal network comprising at least one inductor 2 in a series arm, at least one differential capacitor 3, and possibly a series coil and a resistor. The differential capacitor lies in an input or output shunt arm, and its rotor is connected to a tapping of the inductor. The fundamental attenuation is set by a resistor R, which is either connected in a shunt arm to a common or further tapping of the inductor or is connected in parallel with the inductor. The circuit can be employed as a continuously adjustable attenuation corrector in carrier frequency systems. <IMAGE>
