Hint
Question 1 (10 points)
You are tasked with setting up a video Zoom meeting in your company’s conference room. The conference room is equipped with a Logitech Conference Video Conference Webcam, which includes a built-in speakerphone. The microphone has a bandwidth of 200 Hz to 8 kHz. The camera transmits video using a resolution of 1280 x 720 pixels, with each pixel capable of displaying one of 32 intensity values. The video is transmitted at a rate of 30 frames per second.
Find the video Data Rate R (bps). (5 points)
Assume that the Zoom conference is transmitted over a CAT5 10/100 Mbps Ethernet cable operating at 800-MHz bandwidth and a -35dB signal-to-noise ratio. Find the capacity of the channel (bps). (5 points)
Question 2 (5 points)
Consider a noiseless channel with a bandwidth of 9.5 kHz transmitting a signal with four signal levels. What is the maximum bit rate, in bits per second (bps), of this channel?
Question 3 (5 points)
You are tasked with creating a network that has a minimum bandwidth capacity of 50 Mbps. The network channel bandwidth is 45 MHz. Assuming white thermal noise, what level of signal-to-noise ratio is required to maintain this data rate? Please explain your answer and discuss what your findings mean for average network users and technicians.
