- Calculate the theoretical maximum channel capacity of a noisy channel with bandwidth 6 kHz if the signal-to-noise ratio is 27 dB. Give your answer to 3 significant figures and state what noise properties are assumed.A line has a signal-to-noise ratio of 1000 and a bandwidth of 4000 kHz. What is the maximum data rate supported by this line? If the bandwidth of the channel is 5 kbps, how long does it take to send a frame of 100,000 bits out of this device? What is the maximum data rate of a channel with a bandwidth of 200 kHz if we use four levels of digital signaling?A digitized voice channel is made by digitizing a 4-kHz bandwidthanalog voice signal. We need to sample the signal at twice the highestfrequency. We assume that each sample requires 16 bits. What is therequired bit rate?
