Answer 1

Amplifier is a device whose output is an enlarged reproduction of the essential features of the input wave and which draws power from a source other than the input signal.

Null type device measure and generates an opposing effect to maintain zero deflection.

Transducer is a device that converts input energy into a form of an output with different form of energy.

Accuracy is the ratio of difference between measured value and true value of the measurand. Resolution is the smallest increment in measurand that can be detected with certainty by the instrument.

Precision is the ability of the instrument to give identical output measurements when repeat measurements are made with the same input signal.

Drift is the gradual departure of the instrument output from the calibrated value.

Backlash is the maximum distance or an angle, any part of the mechanical system can be moved in one direction without causing the motion of the next part.

Linearity is the characteristic of the instrument whose output is a liner function of the input.
