Channel capacity:
  • Channel capacity is the maximum rate at which the data can be transmitted through a channel without errors.
  • The capacity of a channel can be increased by increasing channel bandwidth as well as by increasing signal to noise ratio.
  • Channel capacity (C) is given as, 
Where,
B: Bandwidth
S/N: Signal to noise ratio
Entropy:
The entropy of a probability distribution is the average or the amount of information when drawing from a probability distribution.
It is calculated as:

pis the probability of the occurrence of a symbol.
