Consider the unity feedback negative system with an open-loop function G(s)= K (s^2+10s+24)/(s^2+3s+2).

a. Plot the locations of open-loop poles with X and zeros with O on an s-plane.

b. Find the number of segments in the root locus diagram based on the number of poles and zeros.

c. The breakaway point (the point at which the two real poles meet and diverge to become complex conjugates) occurs when K = 0.02276. Show that the closed-loop system has repeated poles for this K.

d. The break-in point (the point at which the complex conjugate poles meet and diverge to become real) occurs when K = 10.97. Show that the closed-loop system has repeated poles for this K.

e. Find the poles of the closed-loop system when K = 6.

f. Sketch the two segments of the root locus.

Implement the synchronous 2-bit Up/Down counter  with saturation at the end states. The flip-flop outputs Q1, Q0 serve as the outputs of the counter.

The counting direction is set with mode control input M.

With M =1 the flip-flop outputs follow the incrementing binary sequence starting from a current state with saturation at state 11 as shown in the following example: 00-> 01-> 10-> 11-> 11-> 11...

With M =0 the outputs follow the decrementing binary sequence from a current state with saturation in state 00 as illustrated below:

11-> 10-> 01->00->00->00...
