ABSTRACT:
A truncated frequency discriminator according to the present invention features an amplifier (A), phase adjustment circuits (CAP1, CAP2) and circuitry (V1, V2) for very weakly forward polarizing Schottky diodes (DS1, DS2). Such a truncated frequency discriminator allows for a reduced noise and may find particular application in optical telecommunications receivers.
