Process Control and Instrumentation In a second order under damped system, the Overshoot (which is a measure of how much the response exceeds the ultimate value) increase with the decrease of damping co-efficient e Decay ratio (which is the ratio of the sizes of successive peaks) is equal to the reciprocal of overshoot None of these Time required for the response of first reach its ultimate value is called the response time Overshoot (which is a measure of how much the response exceeds the ultimate value) increase with the decrease of damping co-efficient e Decay ratio (which is the ratio of the sizes of successive peaks) is equal to the reciprocal of overshoot None of these Time required for the response of first reach its ultimate value is called the response time ANSWER DOWNLOAD EXAMIANS APP
