Circuit Builder
• . Binary Logic The objective is to devise and to piece together a series of binary logic elements to effect an ultimate mathematical operation such as addition, or subtraction, or multiplication.
• . It is necessary and sufficient to consider logic elements for which there are two binary inputs and one binary output.
• . We consider three logic elements from which all binary logic may be constructed: the AND, OR, and NOT gates.
• . To build your circuit, drag logic components into the circuit area.
• . Once these inputs are specified, the state (1 or 0) of each logic line will be displayed.
• . Click to view the available logic elements, their graphic representation, and their input/output tables.
• . That is, use the to establish the logic behavior of AND, NOT, OR, NAND, NOR.
• . Using only the component NAND, create a circuit that is equivalent to the logic of an AND gate.
• . (If this is doable, it means that all binary logic circuitry can ultimately be generated from the single logic element NAND).

Power Searching and Power Learning with Digital Logic
• From Now On The Educational Technology Journal Vol 7|No 4|January|1998 Searching for the Grail? Power Searching with Digital Logic by Jamie McKenzie No sense sending students and colleagues out to search the Internet or a CD-ROM encyclopedia unless they possess a toolkit of powerful search strategies to speed them past Info-Glut and Info-Garbage to the very information they need.
• . Boolean Capabilities Learning how to use logical operators such as AND , OR and NOT greatly enhances your searching.
• . Fuzzy Logic usually produces fuzzy search results.
• . Is larger better? Digital Logic Many search engines employ artificial intelligence and digital logic to determine relevancy, proximity and other issues which might help you find the best information.
• . Browse before grazing Early search efforts are meant to provide an overview of the information landscape relevant to the investigation at hand, much like petroleum prospectors flying over a region and noting the terrain, seeking convergence (a combination of geological elements in one location which hints at the presence of oil).

Welcome to Play-Hookey!
• . Digital logic is at the core of all digital computers, and yet it is entirely based on three fundamental operations, designated AND, OR, and NOT.
• . Meanwhile, tests have shown that IE4 and higher can also handle the current interactions in the digital logic section.

Logic Gates - Digital Logic Circuits
• Understanding Logic Gates 2 of 32 LOGIC GATES Logic Gates are circuits made up of transistors, diodes, and resistors.
• . Logic gates process one or more input signals in a logical fashion.
• . Depending on the input value or voltage, the logic gate will either output a value of '1' for ON or a value of '0' for OFF.
• . Logic Gates allow simplification of circuit operation.
• . A basic understanding of logic gates will aid technicians in electrical diagnosis.

Digital Logic MetaStability and Flip Flop MTBF Calculation
• Digital Logic Metastability Definitions listed in Logical order.
• . Metastable: A state which exist between either "valid" digital logic state {an undefined voltage} Digital Logic State: A defined range of voltages that indicate which logic level the device will switch to, or resides in.
• . For TTL, a logic low is {0 to .8 volts}, a logic high is {2.4 to 5 volts} .
• . Undefined Voltage: A voltage between the established logic level, either High or Low; {.8 to 2.4 volts} from the example above.
• . Ambiguity: The uncertainty in the amount of time it takes for a valid logic signal to change from one state to another.
• .
