## Study Notes

### Karnaugh Maps

- A three-variable map has 2^3 = 8 minterms.
- In a Karnaugh map, a cell that corresponds to a maxterm in the Boolean expression is a cell that is empty or has a 0.

### Boolean Functions

- The simplified form of F(w, x, y, z) = y' + x'z' + w'xz using the Karnaugh map can be determined.
- The function F(w, x, y, z) = ∑0,1,2,3,4,5,6,7,8,9,11 represents 11 minterms.

### Logic Minimization

- A five-variable map consists of 2^5 = 32 cells.
- Don't-care conditions are used in logic minimization to specify the output of a function for certain combinations of variables.

### DeMorgan's Theorem

- Applying DeMorgan's theorem to the function F = A'B'E' + BD'E + ACE results in F = (A+B+E)(B'+D'+E')(A'+B'+C').

### NAND Gates

- The two-level logic equivalent of F = AB + CD implemented using NAND gates is F = (A NAND B) NAND (C NAND D).
- The correct implementation of F = xy' + x'y + z using NAND gates is F = (x NAND y') NAND (x' NAND y) NAND (z NAND (x NAND x')).
- The function F = (AB' + A'B)(C + D') is equivalent to F = (A NAND B') NAND (A' NAND B) NAND (C NAND D') when implemented using NAND gates.

### Product-of-Sums Form

- The simplified form of F = S(0, 1, 2, 5, 8, 9, 10) into product-of-sums form can be determined.

### Logic Implementation

- A five-variable map consists of 32 cells.
- Implementing AND-OR logic using NAND-NAND logic is a possible implementation.
- The value of a function should be specified for certain combinations of variables when using don't-care conditions.

### Universal Gates

- The NAND gate is considered a universal gate that can implement any digital system.
