Abstract
Time-division multiplexing allows 24 channels of evoked potential data to be recorded on a seven track instrumentation tape recorder and later played back into a signal averager where it is simultaneously demultiplexed and averaged. Complimentary metal-oxide-semi-conductor (CMOS) switches provide a simple, low-cost way of increasing the number of recorded channels when the bandwidth of the recorder is sufficiently high.
