Abstract :
A simple time-division multiplexing system composed largely of commercially available units frequently found in biomedical laboratories is described. It can be used either with the intermediary of magnetic tape recorders or directly, for transmission of two or three channels of information over a single communications link. Possible selection of operating parameters is extremely wide, permitting optimization of channel capacities for particular signals such as electroencephalograms, electrocardiograms, electro-oculograms, tremograms, etc.
