what are the difference between analog and digital instrument?
27008
Difference between analog instruments and digital instruments. The instrument which gives output that varies continuously as quantity to be measured is known as analog instrument. The instrument which gives output that varies in discrete steps and only has finite number of values is known as digital instrument.

KEY DIFFERENCES: An analog signal is a continuous signal whereas Digital signals are time separated signals. Analog signal is denoted by sine waves while It is denoted by square waves. ... Analog signals are suited for audio and video transmission while Digital signals are suited for Computing and digital electronics.

There are two primary types of multimeters, one begin the analog and the other is the digital. The primary difference between the two is the display, an analog multimeter uses a needle to show the value, while a digital multimeter will show the results as numbers on a screen.

A digital sensor only detects two possible status: if it is working at 100% or at 0%. An analog sensor measures continuously the variable and detects any proportional value between 100% and 0%. For this reason, the measure provided by the analog sensor is more precise than the one provided by the digital sensor.

Analog scales are considered to be more accurate but the fact is that they are not precise. This has a trade-off. Digital scales are considered to be a lot of precise but one thing that you might want to understand is that there is a slight percentage of error in every reading.

Analog Computers The basic difference between analog and digital computers is the type of data they process. ... Digital computer process data which is binary, i.e. in the form of 0 and 1. Analog computers operate on mathematical variables in the form of physical quantities that are continuously varying.

Analog and digital circuits are used to transmit and process the information like sound, light from an environment to generate continuous variable signals. ... To get the outputs, analog circuits can directly give the signals while a digital circuit has to change the information back to an analog signal.

Analog Electronics deals with Analog Signal which is a continuous signal , means it varies continuously with time. Most of the signals in nature are of analog in nature. Digital Electronics deals with digital signal which is discrete signal. ... Digital Data can be easily coded ( encrypted ) for security.
