摘要： An equalizer and an equalizing method are provided to converge tap coefficient at high speed according to the profile of a received signal. The equalizer includes an input signal position ver¬ ification block verifying a position change between a signal currently received by the tuner and a previously received signal; and a coefficient position adjustment block determining a position of a tap coefficient outputted from the tap coefficient update block by referring to the position change of the currently received signal verified by the input signal position verification block. The convergence speed of tap coefficients can be increased, and the performances and speed of the receiving system can be improved.
