Signal decoding electronic component for digital television, has filtering stage in base bands arranged on two channels at output of transposition stage, and default error correction stage matching phase and amplitude of channels

摘要

The electronic component has a tuner (TZ), which is ascending and descending with null intermediate frequency. A band pass filter includes surface acoustic waves between two frequency transposition stages of the tuner. A filtering stage in base bands (FBBI, FBBQ) is arranged on two channels at an output of the transposition stage. A default error correction stage (MCOR) matches phase and amplitude of the channels. An independent claim is also included for a receiver of a terrestrial digital television signal.
