Analog Computation Part I
Analog Computer The computer which is used to process analog data is known as analog computer. Analog computers are mainly used for situations which require data to be measured directly without converting into numeral or binary codes. These computer mainly used for scientific and engineering applications. The heart of the analog computer is a device called an operational amplifier, because it can be used to perform many mathematical operations, such multiplication, division, integration, and differentiation, on the input signals. as addition, subtraction,
What is an Operational Amplifier (Op-Amp)? An operational amplifier is a directly coupled high gain voltage amplifier. It is basically a differential amplifier that amplifies the difference between two input signals. Name derives from its use to perform various mathematical operations such as addition, subtraction, integration etc. on an input signal.
