The subsequent problems deal with the circuit below where the preset and clear features operate based on positive logic (i.e., they are "active high"), which is not the standard convention.
Note: Each question is independent and doesn't depend on results from previous questions. The only values known initially are the values provided in each question.When L=0, C=1, and R changes from 0 to 1, the output X
A. becomes (or remains) 0 B. remains unchanged (regardless of whether the initial value is 0 or 1) C. toggles regardless of its value D. is uncertain E. becomes (or remains) 1
In a parallel RLC just below the resonant frequency, the impedance is:
A) at maximum. B) more capacitive. C) more inductive. D) at minimum.
In the feedback system in Figure E.22, graph the response of the system to a unit step, for the time period, 0 < t < 10, then write the expression for the overall system transfer function and draw a pole-zero diagram, for the given values of K.
(a) K = 20
(b) K = 10
(c) K = 1
(d) K = ?1
(e) K = ?10
(f ) K = ?20
