ABSTRACT:
A channel equalizer for a digital television receiver which filters an input signal to remove a noise component mixed therewith during transmission. The channel equalizer comprises an initial coefficient storage unit for outputting a predetermined coefficient to channel equalizer circuit when a certain channel is firstly selected. The predetermined coefficient is used as an initial filtering value for allowing the channel equalizer circuit to update a filtering coefficient so that it can converge on an optimum value. The stored filtering coefficient is output to the channel equalizer circuit when the firstly selected channel is again selected, so that it can be used as the initial filtering value.
