Assume a digitized TV picture is to be transmitted from a source that uses a matrix of 480 x 500 picture elements (pixels), where each pixel can take on one of 32 intensity values, and that 30 pictures are sent per second.
(a) Assume a channel exists with a 4.5MHz bandwidth and a 35dB signal to noise ratio. Calculate the capacity of this channel and determine if the TV signal can be transmitted on it.
(b) How much could the bandwidth of the channel be reduced and still be able to send the signal?
(c) How much could the signal power be reduced and still be able to send the signal?
