Abstract : A new, simple, data-reduction device was designed and constructed. It consists of a standard playback and discrimination system for tape-recorded telemeter signals; an electronic system for the scaling of time signals; an an optical-mechanical system which simultaneously records on film a horizontal scale grid which may be nonlinear if the function requires it, vertical timing lines, and the galvanometer trace of the telemetered function. This device produces a continuous graphic plot of telemetered information on a linear or nonlinear scale (as may be necessary) with an accuracy within one per cent of manual plotting methods but in about 1/20 of the time. It requires complex electronic circuitry for the timing pulses only, yet it produces a trace of comparable quality to that of far more complex machines. (Author)
