FIXED TOLERANCE BAND COMPACTION

Data compaction accomplished by storing or transmitting data only when the data fall outside prescribed limits. Note: An example of fixed- tolerance - band compaction in a telemetering system is the transmission of the temperature only when the temperature is above or below preestablished threshold limits. Thus, the recipient of the transmission is to assume that the value is in the prescribed range unless a signal to the contrary occurs. [ From Weik '89 ]
