<p>In an adjustable frequency-dependent equalizer for correcting the distortions at the ends of the passband of a filter, which equalizer has an L-, a T- or a bridget T-configuration and comprises a series-resonant circuit, a capacitance is connected in parallel to the inductance of said series-resonant circuit. The two capacitances are varied so that their sum is kept constant.</p> |
