NOT Gate Also known as an inverter
What are digital circuits?System of logic components that model some Boolean expression Inputs Digital Circuit Output Example: ~x · y = z
Example – Circuit ExpressionWhat Boolean function does the following digital circuit model? Answer: ~x + ~y = z
Example – Circuit ExpressionWhat Boolean function does the following digital circuit model? Answer: f = xy + yz + ~xz
Your Turn What Boolean function does the following digital circuit model?
Example – Expression CircuitDraw the logic circuit that corresponds to the following Boolean expression: f = ~(xy+z)
Example – Expression CircuitDraw the logic circuit that corresponds to the following Boolean expression: f = ~(x+z)·(x+y)
Your Turn Draw the logic circuit that corresponds to the following Boolean expression: f = xy + ~xy + ~(yz)
NAND Gate ~(xy)
NOR GATE ~(x+y)

CIS 6001 Gates Gates are the building blocks for digital circuits Conventions used is high voltage = 1 and ground = 0 Inverter and NOT Gate are two terms.
In this module you will learn: What the various logic gates do. How to represent logic gates on a circuit diagram. The truth tables for the logic gates.
TODAY YOU ARE LEARNING to explain why data is represented in computer systems in binary form 2. to understand and produce simple logic diagrams.
