The purpose of this handbook is to provide practical information about telemetry system engineering. This handbook is intended to be useful to both system designers and operators. This handbook is divided into five sections: 1. Introduction, 2. Telemetry terminology, 3. Telemetry signals and noise, 4. Telemetry transmitting system characterization, and 5. Telemetry receiving system characterization. The subject discussed include: 1. Parameter optimization for best data quality, 2. Radio frequency spectral ...
The patent relates to an apparatus for injecting a signature signal on a magnetic tape, comprising a signature signal generator connected to a switching system. The switching system connects the signature signal to the recorder inputs while disconnecting the normal recorder inputs. A timer is located in the switching system to permit the injection of the signature signal for a specific time period.
