Abstract: A partial fractionally spaced equalizer for a digital television includes, a feedforward filter unit for receiving an input signal sampled at a predetermined frequency, which is divided a first region having a symbol spaced tap and a second region having fractional spaced taps narrower than the symbol spaced tap, a feedback filter unit having symbol spaced taps, a equalizer signal generator for processing feedforward tap signals outputted from the feedforward filter unit and the feedback tap signals outputted from the feedback filter unit and generating equalizer signals, a slicer for slicing the equalizer signals to generate a decision data and outputting the decision data to the feedback filter unit, and an error generator for generating a compensating error signal by subtracting the equalizer signal from the decision data. When a sampled input signal (Si) of 21.

Abstract: A vestigial sideband VSB receiver for receiving signals which are transmitted by being modulated in a vestigial sideband method and a carrier wave restoring method are disclosed, in which the VSB receiver includes a digital processing part for selecting a desired channel frequency via an antenna and converting the desired channel frequency to an intermediate frequency to digitalize a predetermined band of the intermediate frequency, a carrier wave restoring part for extracting pilot components from a signal of the digitalized pass band to restore carrier waves, and a demodulator for separating components I and Q from signal of the digitalized pass band and multiplying the components with a complex carrier wave, which is restored in the carrier wave restoring part, wherein the carrier waves are restored by extracting the pilot signals from the pass band and the symmetrical errors of the carrier wave frequency is detected, so that the carrier wave may be stably obtained and pursued with relation to the both pos
