Channel capacity or transmission information ability, is the maximum symbols number which can be transferred through the channel per unit time.
The maximum number of 6 MHz channels which can be simultaneously carried on a CATV system.
Maximum discharge that can be contained within the banks of a channel.
The maximum data traffic that can be handled by the channel.
Maximum number of channels that a cable system can carry simultaneously.
In computer science, channel capacity, is the amount of discrete information that can be reliably transmitted over a channel. By the noisy-channel coding theorem, the channel capacity of a given channel is the limiting information transport rate (in units of information per unit time) that can be achieved with vanishingly small error probability.
