Automatic Control Systems A conditionally stable system is stable for the value of gain between two critical values. It is unstable if None of these Both A and B The gain is increased beyond upper critical value The gain is decreased below lower critical value None of these Both A and B The gain is increased beyond upper critical value The gain is decreased below lower critical value ANSWER DOWNLOAD EXAMIANS APP
