Describe the action of logic gates. • AND, OR, NAND, NOR, NOT, XOR and XNOR • Using Boolean expressions. • Using truth tables. Understand the use of universal gates. • NAND • NOR containing standard logic gates.
3 Ιουν 2024 · Logic gates are the simplest combinational circuits. As we saw in part 1, their output is a very simple function of their inputs describable with a very simple truth table.
Draw your own combination of two logic gates and a completed truth table. Use the logic lab at http://www.neuroproductions.be/logic-lab/ to test your predictions.
Logic Gates • Basic logic circuits with one or more inputs and one output are known as gates • Gates are used as the building blocks in the design of more complex digital logic circuits

The basic logic gates are the inverter (or NOT gate), the AND gate, the OR gate and the exclusive-OR gate (XOR). If you put an inverter in front of the AND gate, you get the NAND gate etc. One of the common tool in specifying a gate function is the truth table.
