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.
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 CSE370, Lecture 45! Example: F = (AŁB)™ + CŁD! Example: F = CŁ(A+B)™ Mapping Boolean ...
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 ...
Lecture 32. Digital Logic Gates. Reading: Jaeger 6.1-6.4 and Notes. NOT or Inverter Gate: (Asks, is the input false?) Input Output. A Z. Logic Function: Z A. False=State “0” True=State “1” AND Gate: (Asks, are all inputs true?) Inputs. Logic Function: Output. . AB. OR Gate: (Asks, is any input true?) Inputs. Logic Function: Z.
Most modern devices are made from billions of on /off switches called transistors. We will build a processor in this course! Transistors made from semiconductor materials: MOSFET – Metal Oxide Semiconductor Field Effect Transistor. NMOS, PMOS – Negative MOS and Positive MOS.
