1 Answer

Answer :

i) Sensitivity: It is the ratio of magnitude of output signal to the magnitude of input signal. 

ii) Linearity is defined as the ability to reproduce the input characteristics symmetrically and this can be expressed by the equation y= mx+c where „y‟ is the output, „x‟ is the input, „m‟ is the slope and „c‟ is the intercept.
