Describe at least 3 methods to increase data rate in a communication system. What are the pros and cons of each method?

Solution

The three methods to increase data rate in communication system are:

1. Increase bandwidth.

Pros: More data can be sent

Cons: (1) Unnecessary wastage of bandwidth.

         (2) Bandwidth is very rarely available, so we can\'t waste bandwidth.

2. Increase clock frequency.

Pros: We can send more bits, if clock period is more.

Cons: with increase in clock frequency, circuit complexity increases.

3. Use effective modulation technique.

Pros: No wastage of bandwidth, for increase of data rate.

Cons: Complexity of the circuit design.
