A Diode Multiplexer for Analog Voltages

A diode muliplexer switch is described for time-sharing 64 analog voltages in a digital computer application. Apart from its relative simplicity and economy, the multiplexer characteristics of microsecond switching speeds, maximum settling time of 133 microseconds for a 10-volt operating range, and accuracies of better than 1 per cent full scale are confirmed both by theoretical equations and by experimental results.
