Attenuation distortion occurs when some frequencies are attenuated more than other frequencies.
2.
Impedance discontinuities cause attenuation, attenuation distortion, standing waves, daisy chain method of connecting electronic components.
3.
The failure of the line to transfer power at the standing wave frequency will usually result in attenuation distortion.
4.
Attenuation distortion can still occur in a properly equipped circuit if this equalization filter is not properly maintained or adjusted.
5.
The echoed signal is now out of phase and mixed with the original, creating, among other impairments, attenuation distortion.
6.
In DSL circuits, impedance mismatch often cause attenuation distortion so severe that some frequencies must be automatically mapped out and not used.
7.
When an analog signal of constant amplitude across its frequency spectrum suffers attenuation distortion, some frequencies of the received signal arrive being greater in amplitude ( louder ), relative to other frequencies.
8.
Though they used separate incoming and outgoing frequencies, these frequencies were beyond the voiceband for which the cables were designed, and often suffered attenuation distortion due to bridge taps and incomplete impedance matching.
9.
To overcome the effects of attenuation distortion, communications circuits have special equalization equipment attached at the ends of the circuit or in between, designed to attenuate the signal evenly across the frequency spectrum, or to allow the signal to be received at equal amplitude for all frequencies.
