BASIC ELECTRONICS Warning: My WEB is not compatible with multitasking! Student must troubleshoot virtual circuits to benefit from my site. This site aims at teaching the troubleshooting skills required by IT and electronics specialists. This requires that you focus on simulated circuits.

Boolean Operators Multiplication (AND) Addition (OR) Negation (NOT) 0 · 0 = 0 0 + 0 = 0 Not 0 = 1 0 · 1 = 0 0 + 1 = 1 Not 1 = 0 1 · 0 = 0 1 + 0 = 1 1 · 1 = 1 1 + 1 = 1 Note that the AND operator "· " used in Boolean Multiplication operates in a identical manner to the multiplication operator used in arithmetic. The OR operator used in Boolean addition follows the same rules used in arithmetic addition except 1 + 1 = 1 rather than 2. The NOT operator is often written as bar above the variable. ^{ Electronic Logic Gates The three Gates shown schematically below are all that is required to electronically implement the three Boolean operators (AND, OR, NOT) electronically. Logic gates can be made with vacuum tubes, relays, or discrete transistors, but today gates generally reside on Integrated Circuits. Logic Gates operate in a binary mode where each input and output is in either one of two states expressed as: 0/1, True/False, High/Low or On/Off. Truth Tables for GATES The relationship between inputs and outputs of Gates or the effect of Boolean operators can be shown with truth tables. The truth tables for the AND, OR, and NOT operators are shown below. As in regular algebra there are mathematical rules that must be followed. The following basic laws are the same for both Boolean and ordinary algebra. Commutative Law: A + B = B + A Associative Law of Addition A(B + C) Associative Law of multiplication A(BC) = (AB)C Distributive Law A(B+C) = AB + AC Click Here! to troubleshoot a Comparator circuit problem.

New 2014: Free electronics and IT vocational interactive training. This tutorial uses all my ebooks, Labs, and links to create full course curriculum. Click here to start learning now! Virtual Circuit Kits: Also Included as part of our Free System Troubleshooting learning method are: 1. Meter Math (Click here) Troubleshooting Numeric Systems. 2. JavaScript for scientific Calculations (Click here) I teach you how to program and perform electronic calculations simultaneously. 3. Electronic Concepts our best free eBook (Click here) For engineers and technicians.
The Internet provides you with all the graphics and text about
electronics that one can imagine. My site and ebooks are special, because
they provide not only free books, but the books include FREE virtual circuits
to observe and troubleshoot. You get virtual circuits with out the
expense of Brick and Mortar bread boards. Industry does not
need technicians that have simply read about electronics circuits, that is why
electronics schools have laboratories in addition to classrooms. I provide
laboratory manuals combined with virtual circuits for you to troubleshoot. That
makes this site and its free downloads different, if not unique.
Please bookmark my site and download some or all of my free ebooks and
simulations. Free ebook: Force Fields. A E&M physics primer for electronics students. Download Zipped PDF file: Click Here! Read "The Energy Matrix" eZine and learn about alternative energy.
