Unformatted text preview: Number Conversion CSE 210W Student’s Notes This assignment is to give you an appreciation of working with different number systems. You will also learn using LogicWorks to build and simulate simple digital circuits. A knowledge of basic gates is necessary and you should also have an understanding of number systems. Although the equations are given for conversions from binary to decimal, you should be able to deduce the logical relationships between binary, octal, and hexadecimal numbers after this lab. This assignment requires the use of LogicWorks. There is some learning to do to find your way around the screen, control boxes, and other facilities. With a bit of TA help, you will find most of the tasks easy and enjoyable. Prerequisites Knowledge Since this is your initial foray into the digital design process, there are not any knowledge prerequisites to complete this lab, except an understanding of number systems. Software You will need the software LogicWorks and, of course, a web browser and a PDF reader. We assume you have all these in the lab. Objectives There are three things you will learn in this assignment. 1. Construct a logic circuit given the design equations, 2. Exhaustively test a circuit to insure it works as specificed, and 3. Use the LogicWorks to perform the above two tasks. You will (a) Construct the circuit using the various gates provided in the LogicWorks libraries, (b) Provide data input using the binary switches, and (c) Display circuit outputs on binary probes, hex and ASCII displays. 1 Background Decimal, binary, hexdecimal, and octal are some number systems you will use a lot. The decimal number system (base 10) is used for dealing with money, measuring, etc. The computer you are using works in binary (base 2). But we do not read binary numbers as well as decimal numbers. Therefore, for programmers, octal (base 8) or hexidecimal (base 16) is commonlynumbers....
