What is carrierless amplitude/phase (CAP)? - Definition from WhatIs.com


carrierless amplitude/phase (CAP)

Part of the Electronics glossary:

Carrierless amplitude/phase (CAP) modulation was the original approach for modulation of a Digital Subscriber Line (DSL) signal. Discrete multitone (DMT) is now the preferred modulation alternative over CAP.

CAP is closely related to quadrature amplitude modulation (QAM).
