ABSTRACT:
A circuit for providing decision feedback equalization uses a variable gain differential amplifier as a level detector and variable gain adjustment to provide nondelayed positive feedback and bit time delayed intersymbol interference compensating feedback to both enhance the amplitude of the present bit and reduce the intersymbol interference of one or more prior bits in a pulse bit stream.
