You are required to design a combinational logic function with 4 inputs (P, Q, R, S) and a single output (Z). Whenever the minterm value of the inputs (PQRS) matches one of the digits in your SID the function output will be a don't care. Otherwise, the function will output a logical '1' whenever the minterm value of the inputs (PQRS) is a prime number. So that there is no confusion, for the purpose of this assignment, the numbers in the range of 4-bit minterm values that are considered prime are:
0, 1, 2, 3, 5, 7, 11, 13
Draw a truth-table to describe your function.
Plot and group the function on a Karnaugh map.
Deduce a minimal sum of products realisation for the functions making maximum use of don't care conditions.
Part B Function realisation and simulation
Draw a circuit diagram for the implementation of your function using AND, OR, NOT gates alone.
Draw a circuit diagram for the implementation of your function using only NAND gates. Include a justification using Boolean algebra for how the circuit was derived.
Draw a circuit diagram for the implementation of your function using only NOR gates. Include a justification using Boolean algebra for how the circuit was derived.
Simulate both of the circuits on Multisim to demonstrate that they comply with the specification given above. You should include a schematic of your simulation arrangement and evidence of the results. Results should be annotated or explained to detail how they show compliance. The assessor will not do this for you.

Why are there so many different colors
: Plants absorb light energy using special molecules called photosynthetic pigments (predominantly chlorophylls). These pigments absorb most of the visible light except for wavelengths in the green part of the spectrum. Consequently, plants appear g..

Less rules that accepts the same language
: Consider the following Turing MachineM = (Q, !,#,^, !, q0, F), where^ = {7, 8, 9} and! = {1, 2, 7, 8, 9,#}:Here, a transition of the form 9/1,R means that when the head is reading 9, M can legally write 1 and move right. Blank is denoted by #.
