3. Suppose that a digitized TV picture is to be transmitted from a source that usesa. matrix of 480 X 500 picture elements (pixels), where each pixel can take on one of 32 intensity values. Assume that 30pictures are sent per second. (This digital source is roughly equivalent to broadcast TV standards that have been adopted.)Fund the source rate R (bps).b. Assume that the Tv picture is to be transmitted over a channel with 4.5-MH2 bandwidth and a 35-dB signal-to-noiseratio. Find the capacity of the channel (bps).c. Discuss how the parameters given in part (a) could be modified to allow transmission of colorTv signals withoutincreasing the required value for R

Water vapor initially at 10 bar and 400 °c is contained within a piston-cylinder assembly. the water lost heat to the surrounding according to isochoric (iso-volumetric) process until its temperature is 150 °c. the water is then condensed isothermally to saturated liquid. for the water as a system, calculate the work in kj/kg
