/ Digital and analog TV broadcast common-use receiver having single ghost canceller and ghost cancelleration method

摘要

PURPOSE: A digital/analog TV common-use receiver having a single ghost canceler and a ghost cancellation method are provided that an equalizer used when receiving a terrestrial digital TV broadcast is also used upon receiving a terrestrial analog TV broadcast. CONSTITUTION: The first filter coefficient generator(206) uses the first reference signal included in an analog TV signal, and generates the first filter coefficients. The second filter coefficient generator(210) uses the second reference signal included in a digital TV signal, and generates the first filter coefficients. A digital filter(212) filters the analog TV signal by using the first filter coefficients if the analog TV signal is received. The digital filter(212) filters the digital TV signal by using the second filter coefficients if the digital TV signal is received.
