The circumference in Figure E5.39 exhibits a glitch at the output during one of the input signal transitions (harmonious to what happens after a while the circumference in Figure 5.23).

a. Draw its Karnaugh map and particularize the imported implicants.

b. When the circumference jumps from one of the imported implicants to the other in a certain direction, a glitch occurs in y. Which is this transition? In other language, which one of the three input signals must modify and in which control ('0' to '1' or '1' to '0')?

c. Draw the corresponding timing diagram and demonstration the glitch.

d. How can this glitch be prevented?
