Answer :

Need of signal conditioning

The Measured, which is basically a physical quantity as is detected by the first stage of instrumentation or measurement system. The first stage, “detector transducer Stage”, the quantity is detected and is transduced into an electrical form.

The output of the first stage has to be modified before it became usable and satisfactory to drive the signal presentation stage of the measurement stage may consist of indicating, recording , displaying, data processing element or control systems.

Measurement of dynamic physical quantities requires faithful representation of their analog or digital output obtained from the intermediate stage i.e. signal conditioning stage and this places severe strain on the signal conditioning equipment.

The signal conditioning equipment may be require doing linear processes like amplification, attenuation, integration, differentiation, addition and subtraction. They are also required to do nonlinear processes like modulation , demodulation ,sampling ,filtering ,clipping ,clamping etc .These functions are require to faithful reproduction of output signal for the final data presentation stage.
