Abstract: A multiposition microswitch that includes a cavity, a mobile portion made of a deformable material extending above the cavity, at least three conductive tracks extending on the cavity bottom, and a contact pad on the lower surface of the mobile part. The mobile part is capable of deforming, under the action of a stressing mechanism, from an idle position where the contact pad is distant from the conductive tracks to an on position from among several distinct on positions. The contact pad electrically connects, in each distinct on position, at least two of the at least three conductive tracks, at least one of the conductive tracks connected to the contact pad in each distinct on position being different from the conductive tracks connected to the contact pad in the other distinct on positions.

Abstract: A method for sampling an analog radio frequency signal comprising reception of the analog radio frequency signal, sending of the received signal on two analog channels, each channel performing a first signal sampling operation, including a filtering step eliminating signal frequencies that could fold on the useful signal during sampling such that the sampled signal represents a filtered version of the received signal, wherein the sampling frequency is taken to be equal to the frequency of the signal carrier divided by a factor Ndiv1+½, Ndiv1 being an integer number, to bring the useful signal to half of the sampling frequency after sampling.

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.
