Part three of the basics in Digital Systems series explains the NOT OR “NOR” gate, its meaning and how it used in Boolean algebra. 
The fundamentals to Digital Systems relates to 1’s and 0’s (binary numbers). Binary logic consists of binary values and logical operations. Letters of the alphabet designates the ‘A’, ‘B’, ‘C’, ‘X’ and ‘Y’ variables. This series shows how binary numbers, truth tables, Boolean equations, Karnaugh maps and timing diagrams are used to communication within computers.
Narrated along with animation, this NOR gate series’ presentation continues to explain the most significant bit orientation of a truth table, the gate’s truth table and Karnaugh map with two and three variables, and how these gates translates into a timing signal.
