Fundamental errors of telemetry measurement signals

The accuracy and resolution of the received signals are important factors for a telemetry system. The received signals are distorted with respect to the original signals at the measurement location by a number of errors related to the various stages of signal processing and transmission. Quantization errors are produced in digital systems which are used for the acquisition of analog signals. Dynamic errors occur in time-variable signals as a consequence of bandwidth restrictions. Another error category is composed of noise-related errors. Attention is also given to static errors, systematic errors, and random errors. The calculation of the aliasing error and the dynamic error is illustrated with the aid of an example.
