Foundations in Elect
Term | Definition | Examples |
---|---|---|
AND Gate | Digital circuit that uses the AND operation to work. The OUTPUT outcome is HIGH if the INPUT outcome is HIGH. | Unless all the inputs of my circuit on multisim were one in the AND Gate , the output was a zero. |
Capacitor | An electrical device used to store electrical charges. | Capacitors are used in everyday life because they are used as a power conductor. |
Clock | Digital signal in the form of a rectangular pulse train or a square wave. | On a digital clock there is a numerical value shown to signify the time. |
Computational Logic | Digital circuitry in which the output is the outcome of a combination of inputs, independent of the order they were put in. | In my circuit there was a computational logic because all the outputs were dependent on the values of my input. |
Cycle | A series of events that are constantly repeated in the exact same order. | When starting to make anything there needs to be a cycle of what to do. The cycle is to insure everything runs smoothly. |
Datasheet | A printed specification giving instruction of pin configuration, electrical properties, and mechanical profiles of an electronic device. | The datasheet is to help keep track of everything that needs to be done and that is already done. |
Dual in-Line Package (DIP) | Very common IC package with 2 parallel rows of pins intended to be inserted into a socket through holes drilled in a printed circuit board. | DIP insures that no physical damage and is the last stage of the semiconductor device fabrication. |
Fuse | A protective device in a current path that melts or breaks when the current exceeds a certain maximum value. | The fuse insures the device is being protected, when the fuse blows there is too much damage done to the system and the product can no longer be used. |
Large Scale Integration (LSI) | An IC that contains circuitry equivalent to 100 gates or more. | LSI is an IC that is only for circuits with a large amount of gates so X>100 (or equal to) |
Logic Gate | An electrical circuit that performs a Boolean algebraic formula. | Logic gates are always represented by binary, 1 and 0 so there is two inputs and outputs. |
Logic HIGH | The higher or 2 Voltages in a digital system with 2 logical levels. | High logic is the logic 1 and is represented by +5V relative to the ground. |
Logic LOW | The lower of 2 voltages in a digital system with 2 logic levels. | Low logic is the logic 0 and is represented by 0V relative to the ground. |
Medium Scale Integration (MSI) | An IC that contains circuitry the same as more than 11 and less than 100 gates. | MSI is an IC that is only for circuits that are in the middle of the SSI and the LSI so 11<X<100. |
NOT Gate | INVERTER gate or an inverting buffer. A logic gate that changes its input logic level to the opposite state. | In circuits with a NOT gate the outcome is different every time the switch is toggled because the input logic level changes to the opposite. |
OR Gate | Digital circuit that uses the OR operation. The output is HIGH (logic level 1) if any or all inputs are HIGH. | The OR gate needs to have a High logic level at least in one of the input for the output to be at a High logic level as well. |
Plastic Leaded Chip Carrier (PLCC) | A square IC package with leads on all 4 sides designed for surface mounting. | It is a reduced cost development of the ceramic lead less chip carrier. |
Printed Circuit Board | Insulating board containing conductive tracks for circuit connections. | Assurance integrated circuits and other electronic components fixed, and support mechanical assembly. |
Schottky TTL | A subfamily of TTL that uses a basic TTL slandered circuit except it uses a Schottky barrier code (SBD) connected between the base and the collector of each transistor for faster switching. | TTL type but a Schottky TTL uses a Sckotty barrier code. |
Seven-Segment Display | Array of 7 separately controlled light-emitting diodes (LED) or liquid crystal display (LCD) elements, shaped like an 8, which can be used to display decimal digits and other characters by turning on their specified element. | Random number generator had a seven-segment display because it had 7 leds. |
Simulation | Testing design function by specifying a set of inputs and observing the outputs results. Simulation is generally shown as a series of inputs and outputs waveforms. | We simulate on computer to insure experiment works before we apply it to the real circuits. |
Small Outline IC (SOIC) | IC package similar to a DIP, smaller, which is designed for an automatic placement and soldering on the surface of a circuit board. | SOIC helped us when soldering because we were able to solder quickly. |
Small-Scale Intergation (SSI) | Integrated circuit with 12 or less gates in a package. | SSI only used on circuits with low amount of gates X<12(or equal to). |
Solder Bridge | An unwanted formation of a conductive path of soldering in between conductors. | Soldering bridges is when the solder from one part connects with the soldering from another part to create a bridge or a line connecting the two solderings. |
Tinning | Process of applying a thin coat of solder to materials prior to being soldered. ex. Applying a light coat of solder to a filament of a conductor to hold the filament in place prior to soldering the conductor. | We tinned our on the materials before we soldered on our pieces to the board. |
Toggle | Switch from 1 effect, feature or state to the other. | Toggle is to switch from a 0 to a 1 and vise versa. |
Transistor | Derived from "transfer resistor." Semiconductor devices that can be used as an amplifier or an electronic switch. | Transistors amplify a switch. |
Transistor- transistor (TTL) | A family of digital logic devices whose basic purpose is the bipolar junction transistor. | TTL helps make integrated circuits. |
Truth Table | List of all possible input values to a digital circuit, listed in ascending binary order, and the output response for each input combination. | Truth Tables help make a list of all the inputs and the outputs for later reference. |
Sequential Logic | Digital circuitry where the output depends not only on the states of the input but also on the sequence in which they work. | Dependent on the input and the order in of the input. |
