Question

difference between linear and non linear amplifier​

Answer 1

If you graph the output signal versus the input signal for a linear circuit, then the graph will be a straight line for all input signal level. With a nonlinear circuit, the output will not be a straight line. ... You input an AC sinusoidal signal, but you get out a DC voltage plus a non-sinusoidal wave.

Answer 2

$\huge\sf{\underline{\underline{\maltese{Answer}}}}$

• The output voltage or current which is directly proportional to either input voltage or current are called LINEAR Op-Amp Circuits. A NON LINEAR OP-Amp is one in which the output signal is not directly proportional to the input signal.
