    Abstract: A COFDM demodulator or analogue comprising a fast Fourier transform circuit analyzing a received signal in a window corresponding to a symbol, each symbol conveying several phase- and/or amplitude-modulated carriers, some of which are signaling carriers, and a circuit for positioning said window. The circuit for positioning said window uses the non demodulated signaling carriers.

    Abstract: An isolation trench formed in a semiconductor substrate has side walls and a bottom wall. Spacers are on the side walls and face each other for forming a narrow channel therebetween. The bottom wall and the spacers are coated with an electrically insulating material for delimiting a closed empty cavity in the channel. The isolation trench is applicable to the manufacture of integrated circuits.

    Abstract: A method for measuring with a maximum error E the phase of a substantially sinusoidal signal, of angular frequency nullnull2null/T, sampled with a sampling period T/r, in which the phase is calculated as the time at which a straight line crossing two consecutive samples located on either side of a median value of the signal reaches said value, including the step of selecting number r from a range included between a value r0 and a value equal to from two to three times value r0, such that: 1 E null max t null [ - T r0 , 0 ] null [ t - T r0 null round null ( G null sin null null null null null null null t ) round null ( sin null [ G null null null t + 2 null null r0 ] ) - round null ( G null sin null null null null null null null t ) ] round(x) being the integer closest to a real number x and G being equal to 2iG1, where i is the number of bits on which are coded the samples and where G1 is a term of correction of the amplitude of the sampled signal.

    Abstract: A device for automatically converting a digital sample sequence X(n) inputted at a first frequency fe and converted into an output digital sample sequence Y(m) at a second frequency fs which is smaller than fe. An interpolator-decimator assembly having a decimation rate equal to null, selected so as to correspond to the frequency offset fe/fs is based on a polyphased filter having p tables of q elements each, said filter being designed such that samples X(n) are input at the fe frequency and table components are activated according to clocking of a second clock derived from the fe clock and wherein one clock pulse is removed.
