1 Logic Design Logic design deals with the basic concepts and tools used to design digital hardware consisting of logic circuits Digital devices: airbags, auto-focus cameras, aircraft navigators, cell phones, credit card readers, digital cameras, DVD players, personal computers, portable music players, …

2 Digital vs. Analog Digital signal at any time can have one of a finite set of possible values Analog signal can have one of an infinite number of possible values

3 Benefits of Digital Reliable storage (CD, DVD, …) Compression (MP3, JPEG, …) Reliable transmission (cell phones, digital TVs, …) Conversion from Analog to Digital Technology

4 Digital Encodings and Binary Numbers We can represent any digital data using only binary digits (0 and 1), or bits. ASCII encoding: A 01000001 B 01000010 … … Base ten: decimal numbers (0,1,2,3,4,5,6,7,8,9) Base two: binary numbers (0,1) Base eight: octal numbers (0,1,2,3,4,5,6,7) Base sixteen: hexadecimal numbers (0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F) Why binary numbers?
