What is Analog Computer

Definition: Analog computer is special type of computer, where to use data in continuously form, not discrete, and changeable continues stream of data is known as “Analog Data”. Analog computers can store analog data in the continuous physical quantities likes as electrical potential, fluid pressure, or mechanical motion, and finally it produces the result with using of measures.

Analog computers are used in such areas, where to need data to be measure directly without transforming into numbers. Analog computer uses the programs for transforming of problematic equations into analog circuit.

Analog Computers are used in different application. Below all mention:

Analog Computer Uses

Voltmeter: A voltmeter is going to use to appear the potential difference existing in between two points of an electrical network, and analogue voltmeters consist of a deflecting needle and getting to curve graduated scale on the display screen.

Thermometer: Analogue thermometer lets to use of graduated scale and properties of mercury to fulfil and execute its operations. It also helps to determine the fever level of human body; therefore to diagnose the body temperature is suitable example of analogue computer.

Analogue Clock: An analogue clock is mostly used gadget in our real life. Mostly guys are not known about that analogue clock is an example of analogue computer. It designs to use of quartz crystal that is getting to suspect with the piezoelectric effect.

Seismometer: A seismometer is an analogue device that is used to keep records the intensity of an earthquake. This component is totally kept touch along with earth’s surface. Whenever, earthquake happens then it generates the waves during an earthquake are known as seismic waves, then seismic waves are getting to record them on the graph paper present into setup, named as seismograph.

Speedometer: A Speedometer is also analogue device that lets you to check the speed of your running vehicle. The scale and properties of speedometer is perfect graduated, measure in KM per hour. The speed is getting to point along with of a needle that lets to defect freely as per the analogue signal received by it.

Tide Predictors: A tide predictor is a perfect example of a mechanical analogue computer. It builds to use of mechanical machinery to get note the height of tides at the regular intervals. The location and motion of earth, sun, and moon celestial bodies are very well known, which is why it is easy getting to predict tides in a precise manner.

Flight Simulators:  A flight simulator is also going to use to make an illusion of all issues while providing the training of a pilot. The simulator makes a perfect replica of real cockpit along with using of hydraulic pumps, image generators, sound systems, motion actuators, and so on. These computing components are getting to deal into our real life or analogue signals that lets us to use flight simulator underneath the section of analogue computes.
