Abstract: A method for sampling an analogue radiofrequency signal comprising reception of the analogue radiofrequency signal, sending of the received signal on two analogue 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: A method and system for measuring a time constant RC of an integrated electronic circuit is provided. This integrated circuit may be made up of a first hardware component and of a second hardware component wherein one of the hardware components is a resistive element and the other is a capacitive element. The first and the second hardware components are connected to an inverting input of an operational amplifier of an integrator of a delta-sigma modulator. A DC voltage is applied to the modulator input. The output signal Qs of the modulator is measured with the aid of an analog/digital converter, and the value of the time constant RC is determined on the basis of at least one measurement of the level of the DC component of the output signal Qs of the modulator carried out with the air of a measurement counter circuit.

Abstract: A radio frequency transmitter, of the type supplied with two signals in baseband and in quadrature, I(nT) and q(nT), which are images from two binary streams representing information to be transmitted, 1) provides a first transposition into the digital domain, at an intermediate frequency ω0, for the baseband signals and generates, by combination, two signals of intermediate frequency in quadrature, 2) provides a second transposition into the analog domain, after multiplication by a frequency ω1, followed by a summation of the two signals at intermediate frequency and in quadrature, in such a way that a resultant signal is generated which is found finally around a frequency ω2, where ω2=ω0+ω1. In an advantageous variant, the radio frequency transmitter additionally digitally compensates gain and phase imperfections of the direct conversion.
