|
|
bit / sec
|
|
sec / bit

Explanation:
Detailed explanation-1: -Channel capacity is a maximum information rate that a channel can transmit. It is measured in bits per second (bps). Channel capacity is a rough value as measuring takes into account only the whole amount of data transferred, but leaves out of account communication quality.
Detailed explanation-2: -Shannon’s formula C = 12log(1+P/N) is the emblematic expression for the information capacity of a communication channel.
Detailed explanation-3: -As stated above, channel capacity is proportional to the bandwidth of the channel and to the logarithm of SNR.
