QUESTION 1 Which of the following correctly describes the relationship between the poles of the open-loop system and the poles of the closed-loop system under negative unitary feedback? (More than one answer may be correct.) O The poles of the open-loop system are the same as the poles of the closed-loop system for K = 0. O The poles of the open-loop system are the same as the zeros of the closed-loop system for all values of K. O The poles of the open-loop system are different from the poles of the closed-loop system for all positive values of K. O The poles of the open-loop system are the same as the poles of the closed-loop system for all values of K. QUESTION 2 True or false? The characteristic equation under negative unitary feedback always has complex roots, i.e., the poles of the closed-loop system are complex conjugate pairs, for all K >0. O True False
