DE 2.3 Flashcards
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.
Common Anode Display
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.
Common Cathode Display
A printed specification giving details of the pin configuration, electrical properties, and mechanical profile of an electronic device.
Datasheet
A circuit that uses a binary decoder to direct a digital signal from a single source to one of several destinations.
De-multiplexer
A?detailed description, especially one providing information needed to make, build, or produce something.
Design Specifications
A digital circuit that produces an output code depending on which of its inputs is activated.
Encoder
Two-input logic circuit that produces a high output only when the inputs are equal.
Exclusive-NOR (XNOR) Circuit
Two-input logic circuit that produces a high output only when the inputs are different.
Exclusive-OR (XOR) Circuit
Logic circuit with three inputs and two outputs. The inputs are a carry bit (CIN) from a previous stage, a bit from the augend, and a bit from the addend, respectively. The outputs are the sum bit and the carry-out bit (COUT) produced by the addition of the bit from the addend with the bit from the augend and CIN.
Full Adder
Logic circuit with two inputs and two outputs. The inputs are a bit from the augend and a bit from the addend. The outputs are the sum bit produced by the addition of the bit from the addend with the bit from the augend and the resulting carry (COUT) bit, which will be added to the next stage.
Half Adder
Base-16 number system. Hexadecimal numbers are written with sixteen digits, 0-9 and A-F, with power-of-16 positional multipliers.
Hexadecimal Number System
A circuit that directs one of several digital signals to a single output, depending on the states of several select inputs.
Multiplexer
A number system that has a base of 8; digits from 0 to 7 are used to express an octal number.
Octal Number System
An array of seven independently controlled light-emitting diodes (LED) or liquid crystal display (LCD) elements, shaped like a figure-8, which can be used to display decimal digits and other characters by turning on the appropriate elements.
Seven-Segment Display
A binary number of fixed length whose sign is represented by one bit, usually the most significant bit, and whose magnitude is represented by the remaining bits.
