CHAPTER FOUR
Logic Functions and Gates Representing numbers using transistors is one thing, but getting the computer to do something with those numbers is an entirely different matter. Digital circuitry is used to perform operations such as addition or multiplication, manage data,
Binary Math and Signed Representations
CHAPTER – 3 Binary Math and Signed Representations Representing numbers with bits is one thing. Doing something with them is an entirely different matter. This chapter discusses some of the basic mathematical operations that computers perform on binary numbers along
Numbering Systems
CHAPTER – 2 Numbering Systems Chapter one discussed how computers remember numbers using transistors, tiny devices that act like switches with only two positions, on or off. A single transistor, therefore, can only remember one of two possible numbers, a
Digital Signals and Systems
CHAPTER – 1 Digital Signals and Systems 1.1 Should Software Engineers Worry About Hardware? Some students of computer and information sciences look at computer hardware the same way many drivers look at their cars: the use of a car doesn’t
