Abstract: An electric signal digitizing device includes a line of propagation through which the signal travels and a plurality of samplers (141, . . . , 14N) connected at separate points on the line of propagation, such that each one samples the signal value at the connection point thereof. The device further includes an analog matrix memory including a line of which at least some elements are each connected to a sampler of the plurality of samplers to receive the value sampled by the sampler, and a means for the line-to-line shifting of stored values. An analog-digital conversion means is also provided for the analog-digital conversion of the stored values.

Abstract: An analogue phase shifter with vector modulator is envisioned. The analogue phase shifter has an input stage that provides the generation of a pseudo-basis of four vectors. The analogue phase shifter has a multiphase filter. The analogue phase shifter has an output stage that controls the amplitde of the basis vectors, and acts to recombine them. The input stase is made with a phase opposition signal generator and a multiphase filter. The input stase is made of four variable attenuators. The attenuators are for separate control of the amplitude of each of the basis vectors. The output stage also has a common output providing the summation of four quadrature channels. In one case, the output stage includes two differential amplifiers. In another case the quadrature channels are connected to the common output through buffer amplifier stages, each followed by a summation capacitor.
