2.22 The minimal POS expression for f(a, b, c, d) (0, 2, 4, 6, 8, 9, 12, 13) has two essential prime implicants (a + d) and (a c and a non-essential prime implicant (c d). a. Draw a timing for minimal f (a + d)(a + c) when its inputs change from 000 to acd- 100. Does the circuit produce a glitch? b. Draw a timing for the non-minimal f(a d)(ac)(c +d) when its acd inputs change from acd 000 to acd 100. Note fincludes all its prime implicants. Is there a 1-hazard
