Analog computer is any class of electronic device whereas continuously variable physical quantities like as fluid pressure, or mechanical motion are referred into analogous to the corresponding quantities into issue to be fixed. Now, we will cover many stuffs about what is analog computer with its examples, types, functions, characteristics, and features: Involving with many advantages & disadvantages of analog computer with ease. I make ensure that after reading this article; you will get exactly to know about What is Analog Computer without getting any issues.
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.
Slide Rule is very simplest types of analog computer, and this computer helps to produce approximate result for simple mathematical operations. All users slide the hashed rod to line up along with several marking in the other rod, and it help to read this equipment depend on line up of different kinds of hash marks.
Differential Analysers
Differential Analysers computers were designed to solve for all differential equations. These computers had large size to modern computers, because today those computers fill space like as PC.
Castle Clock
Castle Clock has better representation of several uses to mechanical analog computers. Castle Clock analog Computer was developed by Al-Jarazi. This computer was able to store different programming commands. Castle Clock computer’s height was 11 foot, and it takes round of moon and sun. The computational part of this computer permitted users to set veriable length of the day depends on the running season.
Electronic Analog Computers
Firstly, Electronic analog computer was developed in USA, and initially they were used in the different missiles, airplane layout, and in flight simulator. Electronic Analog Computer contains thousands of vacuum tubes, but further some time replaced by transistors.
Latest analog computers are designed to use electrical signal flowing through several resistors and capacitors, instead of mechanical interaction of their components. The voltage of the signal produces the result in the form of graphic displays. Mostly, these types of computers are enabled for different computing and defense technology system.
Mechanical Analog Computers
Mechanical analog computers are designed along with different components such as gears and lever, in which not use electronic parts. It produces output while turning of gears, and it can perform multiplication and division operations. Examples are – Cosmic Engine, Pascaline, Stepped Reckoner etc.
Pneumatic Analog Computer
These computers use the compressed air in the form of power source that is very simple and inherently analog, and these computers mostly used in the nonresidential building areas.
Hydraulic Analog Computer
First, hydraulic analog computer was developed by Mihailo Petrovic Alas in 1868-1943. Firstly, main objective of designing of this computer is to solve the differential equations.
regularly flowing of electrical pulses, and show output continuously. For example – Side rule and speedometer of an automobile, they are displaying their results in real-time. But this device has less memory unit, so they are only capable to perform few types of calculations. Analog computer is very useful machine to solve the differential equations. The accuracy of result those machines are low but they are faster in speed to digital computers, and they are capable to compute all instructions in parallel form.
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.
