Exercise 4 Nyqusit data rate determines the maximum channel capacity. . State Nygusit formula used to determine the maximum channel capacity. . Given a transmission wire with a bandwidth of 8000Hz and 256 distinct levels, determine the channels maximum capacity . A fibre optic cable can transmit 200 Mbps (million bits per second), assuming a bandwidth of 10 Bbps, how many signalling levels are required. 1Bbps is 1000Mbps. Exercise 5 Given the signal to noise ratio, Shannon's result can be used to determine the maximum channel capacity. . State Shannon's formula. . What is the capacity of a channel where the SNR 1000 and the bandwidth is 8000Hz? . If the bandwidth is 10Mbps and the channel capacity is 200Mbps, what is the SNR
