Low Cost, High Accuracy Instrumentation Tape Recorder

Abstract

The report describes a new magnetic tape recording system for general instrumentation use. The system uses a new type of modulation format and offers good performance at low cost. The system concepts are explored from a subsystem or 'block diagram' viewpoint, and extensions of these concepts are hypothesized. An actual prototype is described, its specifications and performance parameters are given, and the results of its evaluation program are presented. The history of the system from 1967 to 1971 is included for completeness. The differential pulse width modulation (DPWM) concept is considered to represent a significant advance in modulation techniques.
