Abstract: 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.
