Abstract :
Two types of multiplexers are described. They are designed to be used in high gamma radiation environments. Multiplexed signals come from different sensors used for distance, angle or force measurement. A low switching rate (10 Hz) version is designed with RS flip-flop based only on relays and transistors. The high switching rate multiplexer consists of a transistor differential stage to control the transistor chopper. Its maximum switching rate is £ MHz
