Distortion-limited operation
Distortion-limited operation In telecommunication, distortion-limited operation is the condition prevailing when distortion of a received signal, rather than its attenuated amplitude (or power), limits performance under stated operational conditions and limits. Note: Distortion-limited operation is reached when the ...
