Ce signal est appliqué pour cela à un émetteur (2) pour moduler une onde optique qui est transmise par des fibres optiques biréfringentes (B1, B2, B3) après commande de sa polarisation selon un mode TE ou TM dans des organes de commutation (C1, C2, C3). Un récepteur optique (8) restitue un signal hyperfréquence retardé (10). La variation du retard est commandée par des signaux de sélection de retards (S1, S2, S3) commandant les organes de commutation. L'invention s'applique notamment à la réalisation d'un système d'antenne à réseau. The present invention makes it possible in particular to assign a microwave signal (4) with a digitally controllable delay. This signal is applied for this to a transmitter (2) to modulate an optical wave which is transmitted by birefringent optical fibers (B1, B2, B3) after control of its polarization according to a TE or TM mode in switching members (C1 , C2, C3). An optical receiver (8) outputs a delayed microwave signal (10). The variation of the delay is controlled by delay selection signals (S1, S2, S3) controlling the switching members. The invention applies in particular to the production of an array antenna system.

Patent FR2500177B1

Analog/digital signal e.g. audio signal, transmitting device for use in field of measuring instrument probe, has field effect transistor reading signal transmitted by cable without removing portion of signal

The device has a field effect transistor (FET) (Q1) placed at an end of a cable. The FET reads a signal transmitted by the cable without removing a portion of the signal. The FET adapts the signal such that the signal is identical to an output of the cable while adapting the signal to the optimal output impedance. An output of the FET is adapted to an iterative impedance of a load situated at another end of the cable.

14,035. Girardeau, E. June 17, 1912, [Convention date]. Electric oscillations, producing. -Aerials for wireless signalling are supplied with high - frequency alternating current by polyphase generators, arrangements being provided by which the polyphase currents are brought into phase with each other as regards their effects in the aerial. Thus the winding 2, 2 of the generator M may be connected directly to the aerial A, while the winding 1, 1 is connected through a transformer T, so that its effect in the aerial is in phase with that of the winding 2, 2. Tuning-means are provided in each circuit so that the generated currents may be in phase with the generating electromotive forces. The use of two generators in cascade is mentioned.
