8. A crossbar exchange is required to set up5000 calls in the busy hour. The markerholding times may be assumed to beexponentially distributed, with an averageholding time of 0.5 second.(a) Find the number of markers required, if theprobability of a register having to wait for amarker is to be less than 0.2.(b) What will happen if a local crisis causes25 000 calls to originate in the busy hour?

To solve this problem, we can use the Erlang B formula, which is used to calculate the probability…

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
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?

What is the minimum necessary speed? Six computer workstations are connected to a synchronous time division multiplexor. Each workstation transmits a 128 kbps. At any point in time, 25 percent of the workstations are not transmitting. What is the minimum necessary speed of the line leaving the multiplexor? Will the answer be different if we use a statistical multiplexor instead? Explain your reasoning Synchronous TDM (definition and calculations): Statistical TDM (definition and calculations):
