摘要： Various embodiments are described herein for a universal television receiver that is capable of processing television channel signals, that are transmitted according to a variety of broadcast standards, to provide video and audio information for a desired television channel signal. The processing includes producing a coarse channel signal that includes a desired television channel signal and then applying resampling techniques to adjust a normalized bandwidth of the desired television channel signal to generally correspond to the normalized passband of a main filter that is used for each of the broadcast standards.
