Problem #7 – It is desired to send 8 bits with a probability of 0.999999 of getting all bits correct. What bit error rate is required?
This is the same question , not different question , please answer the last one too. Give the virtual circuit tables for all the switches after each of the following connections is established. Assume that the sequence of connections is cumulative; that is, the first connection is still up when the second connection is established, and so on. Also assume that the VCI assignment always picks the lowest unused VCI on each link, starting with 0, and that a VCI is consumed for both directions of a virtual circuit. F connects to A
a) i) With respect to computer simulation, explain the terms: steady state, pseudo random number generator, stopping criteria. ii) A packet router receives packets at a rate of 1 million packets per second. The queue formation in the router is modelled as an M/M/1 queue. If the mean packet length is 1000 bytes, what is the output bitrate (in bps) needed (at the router) to ensure that the Pr(queue > 100 packets) ≤ 0.00001? iii) A Call Centre has no call waiting facility, and so loses blocked calls. What formula is used to evaluate call blocking probability? Use this formula, or a more convenient approximation, to find the call blocking probability if the applied traffic is 50 Erlangs and the number of servers is 50.
Give the value of the IP, auxiliary flag, zero flag, the carry flag, the sign flag, the overflow flag, and the parity flag after each of the following instructions if AX is initialized with 0x1325 and BX is initialized with 0x0EEE. Using NASM Simulator (DOSBox) add ax, 0xFCDA add ax, bx add bx, 0xC002
Q3) A binary source X emits marks and space as the following message: X= MMMMMSSMSM Each time it's transmitted, an error occurs so the received message is: Y= M MMS MSMMSS Find a- Mutual information. b- Information rate R(x) of the source if the source outcomes is 150 bits for each micro second. c- Define the bandwidth required for an AWGN channel for error free transmission of the output in the branch (b) if the SNR is 35DB?
7. An E1 is the European version of our T1. An E1 frame has 32 channels. The first channel is channel 0. All 8 bits of channel O are used for framing. Channels 1 to 15 are used for data or voice and no bit robbing is used or needed. Channel 16 is used for control information on all the voice and data channels. Channels 17 to 31 are also for voice or data. a. How many channels are overhead? b. How many channels can be used to send data? c. What is the overhead and the through put for an E1 frame?

Computer Science Write a C program for the ATmega328PB that continuously toggles bits 1, 3 and 6 of Port B every 250 ms without impacting the other bits of Port B. Initialize bits 1, 3 and 6 to values the of 0, 1 and 0, respectively.

Two devices are connected by a asynchronous serial link (UART) as discussed in class and in the text and lab manual. For all parts of this question, the sender is configured at 28000 baud, 7 data bits, 2 stop bits. Note that ASCI| codes are in Appendix E, page 791. How long would it take to transmit the phrase "YOUR HOUSE IS ON FIRE" from this sender at full speed? (Ignore the quotation marks)
