Suppose you are developing the simulation model of a communication system where the incoming calls are being served by a single service person. Assume the arrival of the calls as well as their service times are random. Identify some entities, attributes, activities, events and states variables for this simulation model.

Write examples of random and deterministic signals in physiological systems.

(c) Write a VHDL code to implement the above counter using conditional statement "case". You need not necessarily use a synchronous load mechanism.

Give an example of an interface module used in a communications system, then explain its basic operation, and the specific function of each of the elements/components of the module.

Please answer all subpart in short please I will like it please..

Explain the key parameters or information that are obtained from a load flow study.

(iii) Describe the purpose of multiplexing in an optical communication system and explain the advantages of multiplexing. (iv) How the performance of this system is measured? Provide an example.

Q1: B- Fill out the following blanks: .3-The first 1- Bus-snooping is used for.......2- Two examples of status-flag registers.... computer that used 32-bit microprocessor was......... 4- The inter-processor communication via .5- If a system uses 16-bit address bus, it can reach memory locations up to.......6- Cache memory uses two algorithms for writing... 7- SRAM is better than DRAM due to.......

I need the answer as soon as possible

I want the solution quickly, please
