In addition to technical applications (like automatic transmissions and musical synthesizers), analog computers are also used to solve specific computational problems of a practical nature.These are generally used to monitor real-world conditions like Wind, Sound, Movement, Temperature, etc.The analog machines are designed for specific purposes.The output of analog devices can be expressed in the form of graphs drawn on the screen of an oscilloscope or on paper, or an electrical signal used to control the operation of a mechanism.Analog computers are mostly mechanical or electrical machines that can perform tasks lik e addition, multiplication, subtraction, and division.Consequently, analog computers differ from common digital computers, which operate only with numbers, or quantities.An essential feature of analog computers is that the quantities that represent digital data change consistently over time.They are used in the fields of technology, science, research, engineering, education, etc. Analog Computers cannot store statistics. The efficiency of this computer increases, when we get the result of the data in the form of graphs etc. Responses are continuously generated for viewing or for conversion into another desired form. In the typical electronic analog computers, the inputs are converted to voltages that can be added or multiplied using specially designed circuit units.
