**Define :- Discrete Memoryless Channel**

A communication Channel may be defined as the path or medium through which the symbols flow to the receiver end. A Discrete Memoryless Channel (DMC) is a statistical model with an input X and an output Y as shown in figure.

During each unit of time ,( the signaling interval ) , the channel accepts an input symbol from X, and in response an output symbol from Y. The channel is sais to be "discrete" when the alphabets of X and y are both finite.

Also,it is said to be "memoryless" and not on any of the previous inputs.
