PURPOSE:To make loss characteristics flat and to obtain a delay equalizer with small size and less amplitude distortion, by adding a resistor in parallel with a series resonace circuit of a branch path to ground of a bridge T-type delay equalizer. CONSTITUTION:A resistor R1 is connected in prallel with a capacitor C2 and an inductance L2 forming a series resonance circuit of a branch path to ground of a bridged T-type delay equalizer. The loss characteristics can be made flat by selecting the resistance value of the resistor R1 so that the loss where the frequency is zero, infinity and at the resonance frequency. Since smaller Q value of the capacitive element can be used, the small sized device can be achieved. Thus, a small sized delay equializer with less amplitude distortion can be obtained. |
