Question | Answer | Examples |
---|---|---|
And Gate | Digital Circuit that implements the AND operation. The output of this circuit is high only if all of its inputs are HIGH. | He knew that in order for it to be an AND gate both he input and output had to be working |
Capacitor | An electrical device used to store electrical charge. | We used the capacitor |
clock | digital signal in form of a rectangular pulse train or a square wave | The clock was ticking in the house. |
combinational logic | digital circuitry in which an output is derived from the combination of inputs, independent of the order in which they are applied. | The combinational logic of inputs are used within the truth table. |
cycle | A series of events that are repeated in the same order. | The cycle within the amount of times the random number generator hit 4 was constant. |
datasheet | A printed specification giving details of the pin configuration, electrical properties, and mechanical profile of an electronic device. | The datasheet we recorded was accurate to what we did. |
digital waveform | a series of logic 1s and 0s plotted as a function of time. | The digital waveform shown was mostly 1 |
dual in-line package | A very common IC package with two parallel rows of pins intended to be inserted into a socket of through holes drilled in a printed circuit board. | We used a dual in-line package for a DE project. |
fuse | A [protective device in the current path that melts or breaks when current exceeds a predetermined maximum value. | The fuse ended up getting burnt within the time of trying to cook. |
large scale integration | An IC that contains circuitry equivalent to 100 gates or more. | The large scale integration had 100 gates within the IC we used. |
logic gate | an electronic circuit that performs a Boolean algebraic function | Logic gate us a circuit |
logic high | the high of two voltages in a digital system with two logic levels. | Logic high has two voltages in the system |
logic low | The lower of two voltages in a digital system with two logic levels. | He didn't know what logic low was |
medium scale integration | An IC that contains circuitry equivalent to more than 11 and less than 100 gates | medium scale interrogation contains circuit equivalently then 11 |
not gate | Also called an inverter gate or an inverting buffer. A logic gate that changes its input logic level to the opposite state. | The not gate switches its input level to the opposite state. |
or gate | digital circuit that implements the or operation. The output of this circuit is high (logic level 1) if any or all of its inputs are high. | In the or gate if the output of the circuit is the input is high |
plastic leaded chip carrier | A square IC package with leads on all four sides designed for surface mounting on a circuit board. | Plastic lead chip career allows four side of the design for surface mounting on a circuit board. |
printed circuit board | Insulating board containing conductive tracks for circuit connections. | Printed Circuit board allows containing conductive tracks for circuit connection. |
schottky ttl | TTl subfamily that uses the basic TTL standard circuit except that it uses a Schottky barrier code (SBD) connected between the base and the collector of each transistor for faster switching. | Schottyky tti switches the transistor the quickest |
seven segment display | An array of seven independently controlled light-emitting diodes (LED) or liquid crystal display (LCD) elements, shaped like a figure by turning on the appropriate element.s | Seven-Segment display controls light emitting diode |
sequential logic | Digital circuitry in which the output state of the circuit depends not only of the states of the inputs, but also on the sequence in which they reached their present states. | Sequential Logic output states depends on input to support sequence |
simulation | Testing design function by specifying a set of inputs and observing the resultant outputs. Simulation in generally shown as a series of input and output wave forms. | we ran a simulation on the computer to see how we should get things done |
small outline ic | An ic package similar to a DIP, but smaller, which is designed for automatic placement and soldering on the surface of a circuit board. | Small out is when you automatically place and solder a piece in the surface |
small scale integration | An integrated circuit having 12 or fewer gates in one package. | Small scale integration is the smallest out of all the integration |
solder bridge | The unwanted formation of a conductive path of solder between conductors. | The solder bridge conducts paths solder between conductors. |
tinning | The process of applying a thin coat of solder to materials prior to their being soldered; for example, application of a light coat of solder to be filaments of a conductor to hold the filaments in place prior to soldering the conductors. | Me and Margie were tinning our conductors. |
toggle | To switch from one effect, feature, or state to another. | The toggle was fun to use with the multi-sim |
transistor | Term derived from "transfer resistor." Semiconductor device that can be used as an amplifier or as an electronic switch. | The transistor within my T-V turns on and off |
transistor-transistor | A family of digital logic devices whose basic element is the bipolar junction transistor. | transistor-Transistor is a bipolar transistor which doesn't know what to do |
truth table | A list of all possible input values to a digital circuit, listed in ascending binary order, and the output response for each input combination. | The truth table provides ascending binary order. |
