Protocol

The status of assignments will be kept on the web.To protect identity, you will be assigned a UNIQUE 3 character code.That is the only identifier that will be used.

Your NAME & CODE must be on every assignment. No ID code = no credit. Period.

Keep papers flat. (NO folding.)Staple if necessary. (NO tearing edge to hold together.)Write only on one side. (NO name or other information on the back.)

Only one assignment should be on a page.If multiple assignments are turned in, place each on a separate page.

You do the assignments on time, and you will excel with a high probability of an A.

This is fun stuff, if you will let it to be.We will do some different things, I promise you will not do in any other class.

We are a TEAM.Let’s work together to make this a pleasant learning experience.

Pre-Quiz

State the reason you are taking the class.Write it out, not just the number

1.Easy A2.Like logic and controls3.Required, no particular interest in logic4.Required, interest in computers & controls5.Give other reason

Chapter 1

Introduction

It is about numbers 0 & 1

• Logic = Philosophy

• Mathematical process

• Binary number system

• Only two digits – 0 & 1

AlgebraJust another oneDifferent number systemSame rules

Note that the number one less than 2n consists of n 1’s

(for example, 24 – 1 = 1111 = 15 and 25 – 1 = 11111 = 31).

Binary Addition

0+0=00+1=11+0=11+1=10This is a sum of 0, with a Carry to next bit

Hexadecimal numbersBinary in groups of four24 = 16

ABCDEF

Weighted codes: 8, 5, 2; sum of each digit times its weight. 8*a + 4*b + 2*c + 1*d =???XS3: decimal is binary equivalent +3; Decimal 0 = binary 3 (011)2/5: error checking; each number has two 1’s and 2 0’sOther codes: ASCII; ASCII 30 = Decimal 1, 31 = 1, etc includes letters and controls5421 & XS3: 10’s complement is complementing each bit and adding 1, like 2’s comp
