help only 2.22 not 2.21

2.21 The prime implicants for f(a, b,c, d)- 2(1, 3, 5,7, 10, 11, 14, 15) are ad + ac and cd. The timing diagram for its minimal expression f=a1+ac is shown in Fig. 2.25. Draw the circuit for the non-minimal f = ad + ac + cd, which includes all its label its internal signals. Draw from acd= 1 1 1 to acd-011. Does the circuit produce a glitch? prime implicants, and a timing diagram for the new circuit when its input change 2.22 The minimal POS expression forf(a, b, c, d) prime implicants (a+ d) and (a+c) and a non-essential prime implicant (c+d).
