The answer is 2 frequencies.
A Full-Duplex QAM 64 K Modem uses two frequencies. One frequency is used for upstream and the other for downstream. A variety of common QAM forms are available and include, 16 QAM, 32 QAM, 64 QAM, and 256 QAM. For example, for domestic broadcast use, 64 and 256 QAM are used for cable modem and digital cable TV. The modulation scheme for this modem uses both amplitude and phase.
Answer:
if we had a set of 10 constraints and solver had to determine which 4 to enforce what would be the binary indicator variables have to sum to make this happen
answer : 6
Explanation:
number of constraints = 10
solver has to determine which 4 to enforce
Hence the number the Binary indicator will have to sum to enforce 4
will be : (number of constraints) - 4
= 10 - 4 = 6
