PURPOSE:To miniaturize an equalizer, by using a differential amplifier as a delay element so as to offer the delay element suitable for large scale circuit integration. CONSTITUTION:A transversal equalizer consists of a signal input terminal 1, a delay circuit 2, a weighting circuit 3, a synthesis circuit 4, a discriminator 5, a control circuit 6 and a signal output terminal 7. The circuit 2 consists of a differential amplifier. This differential amplifier has broad frequency characteristics from DC to several GHz, this delay amount has an almost constant value with respect to the frequency and the differential amplifier is used as a delay element having a broad band. |
