Error Terms
Error. The difference between the returned value and the observed or calculated value. The difference between a computed, estimated, or measured value and the true, specified, or theoretically correct value.
Error Amplifier. An amplifier that receives feedback from a circuit and compares that signal to a reference signal to produce an error output signal.
Error Budget. The bit-error-ratio requirement allocated to the respective segments of a communications system, such as trunking, switching, access, and terminal devices, in a manner that satisfies the specified system end-to-end bit-error-ratio requirement for transmitted traffic.
Error Correcting Code. A code in which each data signal conforms to specific rules of construction so that departures from this construction in the received signal can generally be automatically detected and corrected.
Error Correction Code. [ECC], see Error Correcting Code.
Error Detecting Code. A code used to generate transmission data or appended to transmission data to detect and or correct transmission errors; Hamming Codes or Cyclic Redundancy Codes for example.
Error Detection and Correction. [EDAC].
Error Detector. The component in a servo-system that determines when the load has deviated from
its ordered position, velocity, and so forth.
Error Rate. The amount or number of incorrect data bits in a given sample, as in Bit-Error-Rate.
Error Ratio. Same as Error Rate. The ratio of the number of bits, elements, characters, or blocks incorrectly received to the total number of bits, elements, characters, or blocks sent during a specified time interval.
Error Reducer. The name commonly given to the servomotor in a servosystem. So named because
it reduces the error signal by providing feedback to the error detector.
Error Signal. A signal that indicates that an error has been made by the system or its operator. In servosystems, the signal whose amplitude and polarity or phase are used to correct the alignment between the controlling and the controlled elements. The name given to the electrical output of a control transformer.
Error Voltage. In a feedback system the voltage sampled from the output and sent back to a comparator at the system input to adjust the resultant output signal.
