ABSTRACT:
A frequency response equalizer, particularly for wideband networks, whose purpose is to reduce the influence of parasitic capacitances on the frequency behavior, includes the series arrangement of a first coil, a capacitor, a resistor and a second coil, in parallel with a series resistor, in which series arrangement the coils constitute a bifilarly wound transformer. The transformer includes two main inductances and two leakage sub-inductances, in series with the resistor and the capacitor, being arranged in parallel with the series resistor as an active series resonant circuit.
