Question

What is the theoretical capacity of a channel in each of the following cases: a. Bandwidth: 20 KHz SNRdB= 40 b. Bandwidth: 200 KHz SNRdB= 4 c. Bandwidth: 1 MHz SNRdB= 20

Answer 1

Answer:

Bandwidth is a fixed quantity, so it cannot be changed. Hence, the channel capacity is directly proportional to the power of the signal, as SNR = (Power of signal) / (power of noise). so for example a signal-to-noise ratio of 1000 is commonly expressed as: 10 * log10(1000) = 30 dB.
