Definitions. 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.
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 ...
16 Ιαν 2024 · Digital logic gates are made to form RTL (resistor-transistor logic) or DTL (diode-transistor logic) circuits from discrete parts such as resistors, transistors, and diodes. The most “standard” personal digital logic gates along with their respective truth tables are described below.
What are logic gates? • Logic gates turn ON when a certain condition is true, and OFF when the condition is false – They check whether or not the information they get follows a certain rule • They either spit out the answer true (ON) or false (OFF) • Remember: – True= ON = 1 – False = OFF=0
