Note (General): In the functional mock up test of NAL QSTOL Research Aircraft control system, measurements were planned and conducted with the intention of obtaining both real time results to support the development immediately, and reserved data suitable for academically rigorous and detailed analyses from various points of view. The physical quantities of 208 system variables were converted to analogue voltage signals, and supplied from junction boxes to devices for recordings and analyses. The system characteristics of primary interest in each test were investigated using chart recorders, a two-channel X-Y recorder, an FFT analyser, and a monitoring unit of the on board computers. A pre-processor unit of a mini-computer system converted 64 channels of the analogue data to disk image digital data with a sampling rate of 100Hz for each channael. Up to two hours of test data were temporarily stored in the disk file, and then, as a part of near real time processings, were transferred to magnetic tapes for preservation. A digital filtering and sampling technique, designated the Filtering Sample, was applied to the conversion of the pre-processor unit. The Filtering Sample showed a good anti-aliasing effect within a reasonable increment of the processing work load.
