摘要： Provided are an adaptive analog equalizer and a digital signal receiver having the same. The adaptive analog equalizer includes selective comparing means for comparing the data equalized by the equalizing means to an internal reference value set based on the equalized data to output an error signal e(n); sign inverting means for selecting one of the selective comparing means; and a tap coefficient generating means for accumulating the error signal outputted from the selective comparing means and recognizing the intersymbol interference varying with time to generate an adaptive tap coefficient.
