a) Suppose that a digitized TV picture is to be transmitted from a source that uses a matrix of picture elements (1024* 800 pixels), where each pixel can take on one of 32 intensity values. Assume that 25 pictures are sent per second. Find the source rate R(bps).

b) Assume that the TV picture is to be transmitted over a channel with 4.5 MHz bandwidth and a 29 dB signal-to-noise ratio. Find the capacity of the channel (bps).
