Answer 1

Gain is defined as the relationship between the magnitude of input to the magnitude of output when the system is at the steady-state condition. Gain can be large and small however higher gain and least gain will lead to an unstable system. Gain is simply we can say that it is the rate of the outcome if the output is two times the input gain is two and if the output is half the input the gain is 1/2. Take an example that is a difference between small-signal gain and large signal gain of the amplifier. During small gain, the output power of the amplifier is proportional to the input power that is linear. If the gain is increased beyond that the graph is no longer linear. Because every material has a saturation point. That is if we increase the value beyond its maximum capacity further increase in the gain won't increase the output. So higher gain is always having a saturated output. For a higher gain system, the system becomes noninvertible and nonlinear because the system reaches its saturated state. For lower gain system it is invertible and linear. Small gain system is better if there is a chance of notice in the input.Example: Interconnected systems
