An Airborne Digital Measurement and Recording System with Direct Replay to a Digital Computer

摘要

A self contained system for airborne use is described, which multiplexes information from a number of transducers, converts the signals to digital form, and records with 10-bit resolution on magnetic tape, suitable for immediate replay into the Mercury computer. The computer is programmed to demultiplex the data (with self checking and calibrating routines) and rescale from original transducer calibration curves. Hence the original measurements from each channel are presented in true dimensions against a linear timescale. A description of the computer programme is included. (Author)
