Try making all numbers and letters clrearly readable easy to recognize. You also can type it which I prefer so I can copy all later, paste them in Microsoft Word to enlarge & edit if needed. Thanks for all :)

2. Suppose that a digitized TV picture is to be transmitted from a source that uses a matrix of 480 X 525 picture elements (pixels), where each pixel can take on one of 128 intensity values. Assume that 30 pictures are sent per second. a) Find the source rate R (bps). b) Assume that the TV picture is to be transmitted over a 6-MHz bandwidth and a 35-dB signal-to-noise ratio. Find the capacity of the channel (bps). c) Discuss how the parameters given in part (a) could be modified to allow transmission of color TV signals without increasing the required R value
