Abstract: A dynamic multiple comparison device for real time monitoring of changes in incoming digital words streams. The device includes a memory (12) having N memory cells, a comparison section (13, 11, BD1, BD3, BA1) for making a series of N comparisons, a selection section (RC) for selecting after each N comparison, a digital word, a first writing section (14, BD2, W) for writing the selected N digital words, a reading section (11, BA1, BA2, CL, R) for reading the stored digital words, and a control section (17, LC) for controlling the cyclic operation of the device. The device has applications in nuclear power plant control and monitoring.

Abstract: A system for recording and broadcast studios for time multiplexed bidirectional transmission and switching high-fidelity audio-analog and audio-digital signals and command and control signals. A first bidirectional transmission medium conveys first frames produced by multiplexing the high-fidelity signals and command and control signals between a transmitter and a master receiver. The system also includes a controller with a man-machine interface (26, 32, 33, 34) receiving the high-fidelity signals transmitted by input circuits included in the transmitter and the command and control signals for monitoring in real time the evolution of the various parameters related to the signals, and for controlling in real time the modifications and configuration adaptions in the transmitter.
