Abstract
A transformer circuit is arranged to attenuate spurious signals at undesired frequencies and substantially reduce the distortion of signals coupled through the transformer. The transformer circuit includes an iron core transformer and an active circuit arranged to simulate a lumped element having a frequency dependent magnitude which resonates with the transformer impedance at a desired frequency.
