According to the book the answers are 12.16 A group of 100 sources offers messages with exponentially distributed lengthsto a 1200-bps line. The average message length is 200 bits, including overhead,and each source generates one message every 20 sec. Access to the line is con-trolled by message-switching concentration with an infinite queue. Determinethe following:(a) Probability of entering the queue(b) Average queuing delay for all arrivals(c) Probability of being in the queue for more than 1 sec(d) Utilization of the transmission link

According to the book the answers are
9. In an automatic telegraph switching system incoming messages are stored in a queue until the retransmitting equipment of an outgoing trunk can send them. Messages arrive at the rate of 120 per hour. The times taken to retransmit messages may be assumed to have an exponential distribution with a mean time of 10 seconds. If the probability of losing a message because the store is full must be less than 10-6, how many messages must the equipment be able to store?

It is required to apply repetitive code in order to send the following message [1101] across heavy noise channel which have the value [100001010001], suppose that the number of repetitive is three. 1. How the receiver can correct the errors using repetitive code? 2. Is it acceptable to send financial information via this channel with the help of repetitive code? Explain.
Consider as a simple telephone network consisting of two end workplacesand one intermediate switch with a 1 MHz full duplex trunk between eachend workplace and the intermediate switch. Assume a 4 kHz channel foreach voice call. The telephone is used to make four calls per 8 hour workdayin average, with mean call duration of five minutes. Twelve percent of thecalls are long distance. Analyse and determine the maximum number oftelephones an end workplace can support. Note: Please explain the answer process clearly.
Consider the line of code below. analogWrite(11, 84); The voltage at pin 11 is turns on (at 5V for Uno) and off at 500 Hz. This PWM frequency is the default value for Arduino boards. How many microseconds is the voltage at pin 11 high?
Suppose you wish to increase the maximum clock frequency of the following circuit (without introducing timing violations or modifying the functional behavior of the circuit aside from introducing delay) through pipelining. Some potential locations for pipelining to be added to wires (labelled with numbers 1-10) are shown below: 1 D Q A DQ D Q 10 B D Q DQ C CLK Select all of the wires to which you would add pipeline registers. (Note, it is OK to increase the latency of the circuit, but not the functionality: for any sequence of input combinations, it should produce the same output combinations) If it is not possible, do not select any wires. 01 2 3 4 5 6 7 8 9 10 U 0 2 H
