attenuation distortion
Technical term in computing and signal processing; refers to distortion caused by frequency-dependent attenuation in a transmission line or circuit.
Attenuation distortion is a phenomenon where the signal waveform changes due to the frequency characteristics of the transmission line.
Compound of 減衰 (attenuation) and 歪み (distortion). The exact historical derivation is uncertain; the term is a modern technical coinage.
