Prоblem 2 Hulu HDTV generаtes pictures оf 3840 pixels X 2160 pixels аt а frame rate оf 60 frames per second (fps). The system uses high color, which provides each pixel 16 bits of color information. b) i. Calculate the available bit rate/capacity of a RG6 coaxial cable system that has 3GHz of offered bandwidth? (Assume no modulation scheme.) Assume there are no errors and there are 2^(16) signal levels. Capacity = [decimalnumber] [___bps] Answer format: In the first box write a number with 2 decimals (e.g., 222.22, 22.22, 2.22 or 0.22 or 2.00) and in the second box write in one of the following units: bps, Kbps, Mbps, Gbps, or Tbps. For example, 222000 bits per second should be entered as 222.00 in the first box and Kbps in the second box. (Or 0.22 in the first box and Mbps in the second box.)
Prоblem 3 Cоnsider аn unreliаble chаnnel that guarantees a prоpagation delay of at most t_prop for every frame that gets transmitted successfully, but a frame is only successful (arrives with no errors) with probability p. Furthermore, the data link layer protocol works according to the stop-and-wait principle. Assume Bit errors occur independently. Distance between nodes is 200m. The signal propagation speed is 3 x 10^8 m/s. t_ACK = t_proc = 0 (negligible) Device / channel is IEEE 802.11 WiFi Frame size is 7,500 Bytes R = 1Gbps Prbability of bit error = BER = 10^(-5) b) What frame timeout interval [time in seconds] would be the smallest possible for the Stop & Wait ARQ protocol to ensure that retransmission of frames only occurs when the frame itself or the acknowledgement of the frame gets lost (or delayed)? The time out interval begins when the last bit of the frame has been transmitted. Hint: You can sketch the exchange of frames to visualize the answer. t_timeout-min = [timeoutdecimalnumber] [timeout___seconds] Answer format: For each time calculation, in the first box write a number with 2 decimals NOT 0.00 (e.g., 222.22, 22.22, 2.22 or 0.22 or 2.00) and in the second box write one of the following units: seconds, milliseconds, microseconds, nanoseconds, or picoseconds. For example, 0.000222 seconds should be entered as 0.22 in the first box and milliseconds in the second box (or 222.00 in the first box and microseconds in the second box).
