PCM data collecting and recording system designed for airborne use
P. Knight · IRE Transactions on Telemetry and Remote Control · 1957
A pulse-code modulated data-collecting and recording system has been developed especially for airborne applications. Up to 16 channels of analog data can be sampled at a rate of 150 times per second. The sampled information is converted to 8-bit binary code groups with an accuracy of 0.2 percent and then recorded on magnetic tape. The system also provides for recording, along with the data, time history and voice information. This system is compatible with a UKR-7 ground processing system, resulting in a complete data-reduction system that is fast, automatic, and highly accurate.
