Answer: Dolby AC-3 is 32-640 kbps. Dolby AC-3 supports mono to full 5.1
channels. The .1 channel is for which speaker?

Answer: What is the highest modulation order of QAM possible in a clean
downstream?
>> Bandwidth
Answer: the data-carrying capacity of a network or a data transmission
medium's channel, typically in units of bits per second (bps).
>> LDPC (low density power check)
Answer: improves on forward error correction (FEC) and is more efficient
than Reed-Solomon FEC enabling providers to use higher modulation
orders like 4096 QAM.
>> FEC (forward error correction)
Answer: a method of obtaining error control in data transmission in which
the source (transmitter) sends redundant data and the destination (receiver)
recognizes only the portion of the data that contains no apparent errors.
>> VSB (Vestigial sideband)
Answer: is an OTA modulation method used for broadcast in the ATSC
digital television standard.
>> QAM (quadrature amplitude modulation)
