Channel capacity (C):
The channel capacity is defined as the maximum data rate at which the digital date can be transmitted over the channel reliably.
The various concepts related to channel capacity are:
It is defined as no. of bits transmitted by the transmitted per second. It indicates how fast a signal can be transmitted reliably over the given medium.
This capability depends on following:
- The amount of energy put into transmitting each signal
- Distance to be travelled
- Channel Bandwidth
The b.w of the communication medium should be large enough to transmit the digital signal reliably. An inadequate b.w will distort the signal and introduce errors into the received signal.
