Please log in for more thread options | could someone pls explain why qam is preferred to cap in adsl.also how | can we maximize the existing bandwith From the best of my knowledge... Quadrature Amplitude Modulation -- Allows more data to be stored within each cycle by breaking up each cycle period into sub-periods representing a bit of information whose value depends upon the amplitude of the wave. Carrierless Amplitude Phase Modulation -- Precedes QAM and can't fit the same quantity of data thus it being superceded by QAM. -- Dave http://www.claymania.com/removal-trojan-adware.html http://www.ik-cs.com/got-a-virus.htm | |||||||||||||
