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.
Lecture 11 - Logic gates and Boolean. 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. All possible combination of the inputs A, B ...
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. Naturally, the more inputs there are, the larger the truth table.
4 Combinational Logic. Freely sharing knowledge with learners and educators around the world. Learn more. MIT OpenCourseWare is a web based publication of virtually all MIT course content. OCW is open and available to the world and is a permanent MIT activity.
Introduction to Logic Gates. We will introduce Boolean algebra and logic gates. • Logic gates are the building blocks of digital circuits. Logic Variables. Different names for the same thing. Logic variables. Binary variables. Boolean variables. Can only take on 2 values, e.g., TRUE or False. ON or OFF. 1 or 0. Logic Variables.
The outputs of the gates assume at all times the value of the Boolean function, implemented by the circuit. In contrast, a dynamic circuit relies on temporary storage of signal values on the capacitance of high impedance circuit nodes.
Schematic: A drawing of interconnected gates. Net: Wires at the same voltage (electrically connected) Netlist: A list of all the devices and connections in a schematic. Fan-in: The # of inputs to a gate. Fan-out: The # of loads the gate drives. 4.
