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 120 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
