Feedforward equalizer for DFE based detector

   
   

A feedforward equalizer for DFE based detector is provided comprising a digital to analog converter to convert an analog signal to a digital signal. A feedforward equalizer comprises a high-pass filter and is responsive to the input circuit. The high-pass filter has a low cutoff frequency, has a relatively flat response and has high attenuation at low frequencies. A decision feedback equalizer comprises a decision circuit responsive to the feedforward equalizer, and a feedback filter is responsive to the decision circuit. The decision circuit is also responsive to the feedback filter.

Un equalizador del feedforward para el detector basado DFE se proporciona que abarca un digital al convertidor de análogo para convertir una señal análoga a una señal numérica. Un equalizador del feedforward abarca un filtro high-pass y es responsivo al circuito de entrada. El filtro high-pass tiene una frecuencia de atajo baja, tiene una respuesta relativamente plana y tiene alta atenuación en las frecuencias bajas. Un equalizador de la regeneración de decisión abarca un circuito de decisión responsivo al equalizador del feedforward, y un filtro de la regeneración es responsivo al circuito de decisión. El circuito de decisión es también responsivo al filtro de la regeneración.
