Data Transmission

 This homework covers the second part of Data Transmission Part 2 .  You must show all of your work in Details !  Only giving the answer without showing your work will result in Zero points.  Type up all your work and answers no pictures of solutions and no scanned documents. Your submitted Assignment must be in Microsoft Word Document or PDF Only anything other format I will not Grade your work and submit the homework

 Question 1 (20 points)

Suppose you are tasked to setup a video Zoom meeting in your company conference room. Knowing that the conference room camera is Logitech Conference Video Conference Webcam, with Built-In Speakerphone. The microphone Bandwidth: 200 Hz – 8 kHz  and transmit video using a matrix of (1280 x 720) picture elements, where each element can take on one of 32 intensity values. Assume that 30 pictures are sent per second.

  1. Find the video Data Rate R (bps). (10 points)
  2. 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). (10 points)

Question 2 (10 points)

Consider a noiseless channel with a bandwidth of 7 kHz transmitting a signal with four signal levels.  What is the maximum bit rate, in bps, of this channel?

Question 3 (10 points)

You are tasked to create a network with minimum bandwidth capacity of 50 Mbps, the Network bandwidth of the channel is 45 MHz Assuming white thermal noise, what is the level of signal-to-noise ratio required to maintain the data rate?
