Digital electronics represent signals by discrete bands of analog levels, rather than by a continuous range. All levels within a band represent the same signal state. Relatively small changes to the analog signal levels due to manufacturing tolerance, signal attenuation or parasitic noise do not leave the discrete envelope, and as a result are ignored by signal state sensing circuitry.
In most cases the number of these states is two, and they are represented by two voltage bands: one near a defenitions
reference value (typically termed as "ground" or zero volts) and a value near the supply voltage, corresponding to the "false" ("0") and "true" ("1") values of the Boolean domain respectively.
Digital techniques are useful because it is easier to get an electronic device to switch into one of a number of known states than to accurately reproduce a continuous range of values.
Digital electronic circuits are usually made from large assemblies of logic gates, simple electronic representations of Boolean logic functions

Is a transistors an analog device?
yes transistor is analog device because it can process the analog signal . But it can also used as digital devices as we know transistors are used for manufacturing logic gates and several digital devices as multiplexer and decoder encoder and memories also. it is the basic element of digital devices.
Why must sound card and video on a PC be converted from analog to digital?
Primarily because digital systems are more accurate. Additionally, digital technology is replacing older systems with modern devices because digital devices are often much smaller, and require less maintenance.
Which two devices are considered input devices?
biometric authentication device digital camera
What is the definition of controlled equipment?

Is digital clock a digital device?
1. Generally speaking, a digital clock is a digital device. The "heart" of any clock is whatever is used as its time base, and with a digital clock, some kind of digital timing circuit supplies that time base. From there, digital dividers and other circuits count seconds, and other circuits drive a display. 2. Yes by definition it is.

Digital forensics is the recovery and investigation of computer software found in digital devices. Digital forensics can also be referred to as computer crime. Digital forensics was originally called computer forensics but was changed to encompass all digital devices.
Are liquid filled thermometers digital devices?
Liquid filled thermometers are not digital devices. They rely on the expansion and contraction of a liquid to measure temperature, whereas digital devices use electronic sensors to measure and display temperature readings.
