Digital

1. Relating to the technology of computers and data communications where all information is encoded as bits of 1's or 0's that represent ON or OFF states. 2. A numerical readout.

Digital Computer

A device that manipulates digital data and performs arithmetic and logic operations on such data.

Digital Device

A device that has only two states of operation, on and off.

Digital Electronic Fuel Injection

An early Cadillac electronic fuel-injection system.

Digital Instrument

A display that indicates an activity, such as r.p.m., m.p.h., voltage, or fuel supply, with an electronic readout; used in most Indy cars, though some drivers still prefer analog instruments.

Digital Logic

Circuit elements connected in such a manner as to solve problems using components that have only two states of operation.

Digital Oscilloscope

A type of oscilloscope that uses an analog-to-digital converter to convert the measured voltage into digital information. Three types of Digital Oscilloscopes are digital storage, digital phosphor, and digital sampling oscilloscopes.

Digital Phosphor Oscilloscope

A type of digital oscilloscope that closely models the display characteristics of an analog scope while providing traditional digital scope benefits.

Digital Read Out (DRO)

A method of electronically reading conditions as opposed to an analog readout.

Digital Sampling Oscilloscope

A type of digital oscilloscope that employs equivalent-time sampling method to capture and display samples of a signal, ideal for accurately capturing signals whose frequency components are much higher than the oscilloscopes sample rate.

Digital Signal

A signal whose level has only discreet values, like on or off, 1 or 0, +5v or +0.2 v.

Digital Signal Processing

A feature on some high-end equalizers that creates a spatial effect to make a vehicle sound like a concert hall, a small club or even a stadium. Part of a sound system. Abbreviated DSP.

Digital Speech

Recorded speech broken into tiny units of sound, each having characteristics such as pitch and loudness that can be represented by numbers, becoming the digital code for speech.

Digital Storage Oscilloscope

A digital oscilloscope that acquires signals via digital sampling (using an analog-to-digital converter) It uses a serial-processing architecture to control acquisition, user interface, and the raster display.

Digital-to-analog Converter

A device, generally electronic, used to convert discrete digital numbers to continuous analog signals.

Digitize

The process by which an analog-to-digital converter in the horizontal system samples a signal at discrete points in time and converts the signal's voltage at these points into digital values called sample points.

Digitized

The process of converting an analog voltage signal to a digital equivalent that the computer can understand.

Digs

The drag races.

Diluent

A liquid that extends a solution but definitely acts to weaken the solvent power of the active solution.

Dilution

To make thinner or weaker. Oil is diluted by the unintentional addition of fuel and water droplets.
