Boolean Expression:
9.1.5 NAND Gate
This component is a NOT AND, or inverted AND, gate. Its output is low only when all inputs
are high. Using a NAND gate is the same as having a NOT gate at the output of an AND gate.
NAND gate truth table:
Boolean Expression:
9.1.6 XOR Gate (Exclusive OR)
This component has a high output when an odd number of inputs (1, 3, 5, etc.) is high. An
even number of high inputs generates a low output.
