You Have Been Assigned Your Own Individual Codes For The Letters A B C And Also A Pa 2726190

You have been assigned your own individual codes for the letters A, B, C and also a “parity property”.
You can obtain your codes and parity property by following the FSA codes and party property link below.

You are the central hub for a communication system. Messages come to you as sequences of As, Bs and Cs but coded in binary. Each such binary message is to be followed by a ‘check digit’. This is a final 0 or 1 so that the entire binary message satisfies your parity property.

The parity properties are:

Even 0 The entire message (including the check digit) has an even number of 0s.Odd 0The entire message (including the check digit) has an odd number of 0s.Even 1The entire message (including the check digit) has an even number of 1s.Odd 1The entire message (including the check digit) has an odd number of 1s.

For example if your codes are A = 101, B = 1101, C = 001 and your parity property is Odd 0, the message ABAC would get encoded as 10111011010011. The final character is the check digit. It is a ‘1’ because we want an odd number of 0s. So 10111011010011 is valid, but 10111011010010 and 10111011011100 are not.

Make sure you correctly understand this example before you go further. ABAC is 1011101101001. It has 5 0s, so it already has an odd number of 0s. We have to add a check digit to keep this number odd, so the check digit in this case is 1. If the parity property had been Even 0 the check digit would have been 0.

Your task is to design a binary finite state automaton (FSA) to accept all strings that represent valid messages (for your particular codes and parity property) and reject all others.
This FSA must be DETERMINISTIC, REDUCED and must be in STANDARD FORM.

This project is machine marked. You can submit your attempts as many times as you like and your submission will be marked immediately. You will obtain one of 4 responses:

  • Your machine does not work. It does not process the string “…” correctly. The string that your machine processes incorrectly may assist you in understanding why your machine does not work. — 0 marks
  • Your machine processes all strings correctly, but is not in reduced form. This means that your machine accepts precisely those messages that are valid, but has states which are equivalent. — 5 marks
  • Your machine processes all strings correctly. It is reduced but is not in standard form. This means that your machine accepts precisely those messages that are valid, has the right number of states, but they are not named in the correct order for standard form. — 6 marks
  • Your machine processes all strings correctly, and is in reduced standard form. Your machine is completely correct. — 8 marks

You should submit an answer once you think you have found a deterministic machine for your particular codes and parity property. If it is right, you will be told that it works but is not in reduced form. You can then reduce it, and check that you are still right so far. Once it is correctly reduced, you can then put it in standard form if necessary and submit that answer — hopefully finding that it is completely correct.

My Codes are:-

A = 00000

B = 100

C = 10

Parity = Even 1
