Signal processing device

Abstract

A real time equalizer-enhancer apparatus, comprises: a plurality of analog multipliers (33) having one input (X) connected to the sampled input signal, and the other (Y) input connected to the output of an operational amplifier (34); at least one operational amplifier provided with feedback resistor (35), the output of which is connected to the input of one or more of the said plurality of analog multipliers, and the input of which is connected to one or more summing resistor, and a plurality of summing resistor; (36) connected between the output of each of the said analog multipliers (33) and the input of the operational amplifier (34); means being provided to combine the outputs of the said plurality of analog multipliers according to a predetermined combination rule, means also being provided to subtract said combination of multipliers outputs from prescribed constant bias values, and to feed the results back into the inputs of the analog multipliers (33).
