#### Question 2.8 Question 2.9

## Minimum transmission bandwidth

#### From the simple 8-ary example, we can generalize and conclude that:

#### The minimum bandwidth required for error-free transmission in a baseband channel is given by: #### Bmin = 0.5 x 1/Ts #### where Ts is the symbol period.

#### Knowing that the maximum symbol rate that can be supported on a channel is 2B symbols/second, and with each symbol conveying log2M bits, we can conclude that:

#### The channel capacity for a baseband channel with bandwidth B Hz is: #### Channel capacity C = 2Blog2M bits/second
