Abstract

Impedance compensating amplifier, which is of special application in telecommunication lines, improving its transmission equivalent, equalization, and allowing a reduction of the section of the transmission cables, essentially characterized by being constituted from a dipole circuit series associated with a parallel dipole circuit, both of negative impedance and equipped with its own universal equalizer network, the dipole series being formed by a current transformer coupled to a unit gain operational amplifier, with high input impedance and low output impedance, followed by a voltage transformer that applies this to the network with a phase inversion, there being resistive elements for the attenuation of the amplifier in section and for the stabilization of the conversion factor, the parallel dipole circuit consisting of a voltage transformer coupled to an operational amplifier, similar to the anteri or, and whose output is connected to a current transformer with phase inversion and equipped with elements for the reduction of the attenuation of the amplifier in section and for the constant maintenance of the conversion factor.
