It's complicated
Digital integrated circuit that can be programmed by the user to implement any digital logic function.
What is a PLC Programmable Logic Device?
Digital circuitry in which an output is derived from the combination of inputs, independent of the order in which they are applied.
What is combinational logic?
A type of Boolean expression where several product terms are summed (OR’ed) together.
What is SOP Sum of Products?
A written notation that is part code, part human language.
What is pseudocode?
A series of events that are regularly repeated in the same order.
What is cycle?
A circuit board for wiring temporary circuits, usually used for prototypes or laboratory work.
What is a bread board?
A sequential circuit based on a latch whose output changes when its CLOCK input receives a pulse.
What is a flip flop?
A movement of electrical charges around a closed path or circuit.
What is a current?
multiplication over addition. The property that allows us to distribute (“multiply through”) an AND across several OR functions. For example, a(b+c)=ab+ac.
What is distributive property?
A seven-segment LED display where the anodes of all the LEDs are connected to the circuit supply voltage. Each segment is illuminated by a logic LOW at its cathode.
What is a common anode display?
The instantaneous voltage of a waveform. Often used to mean maximum amplitude, or peak voltage, or a pulse.
What is amplitude?
Two-input logic circuit that produces a high output only when the inputs are equal.
What is an Exclusive - NO (XNOR)?
Type of counter in which each flip-flop output serves as the clock input signal for the next flip-flop in the chain.
What is an asynchronous counter?
Digital signal in the form of a rectangular pulse train or a square wave.
What is a clock?
Digital circuit that accepts binary data from some input source and then shifts these data through a chain of flip-flops one bit at a time.
What is a shift register?
A way of representing some physical quantity, such as temperature or velocity, by a proportional continuous voltage or current. An analog voltage or current can have any value within a defined range.
What is Analog?
Group of flip-flops connected in a special arrangement in which the states of the flip-flops represent the binary number equivalent to the number of pulses that have occurred at the input of the counter.
What is a binary counter?
An electrical device used to store electrical charge.
What is a capacitor?
An algebraic expression made up of Boolean variables and operators, such as AND (-), OR (+), or NOT (-). Also referred to as Boolean function or a logic function.
What is a Boolean Expression?
A seven-segment display in which the cathodes of all the LEDs are connected together and grounded. A logic HIGH illuminates a segment when applied to its anode.
What is a common cathode display?
An integrated circuit having 12 or fewer gates in one package.
What is SSI or Small-scale Integration?
A graphical tool for finding the maximum SOP or POS simplification of a Boolean expression. A Karnaugh map works by arranging the terms of an expression so that variable scans are cancelled by grouping minterms or maxterms.
What is a K Map or Kaurnaugh map?
Digital circuit that implements the AND operation. The output of this circuit is HIGH only if all of its inputs are HIGH. Digital circuit that implements the AND operation. The output of this circuit is HIGH only if all of its inputs are HIGH.
What is an AND gate?
Term derived from “transfer resistor.” Semiconductor device that can be used as an amplifier or as an electronic switch.
What is a transistor?
Theorem stating that the complement of a sum (OR operation) equals the product (AND operation) of the complements, and
2) Theorem stating that the complement of a product (AND operation) equals the sum (OR operation) of the complements
What is DeMorgan's Theorems?
