Using the style of drawing in Figure 3.66 (see below), draw a picture of a PLA programmed to implement fl(x1, x2, x3) = m(1, 2, 5, 6). The PLA should have the inputs x1, x2, x3; the product terms P1, P2, P3, P4; and the outputs fl and f2. ww Figure 3.66. A NOR-NOR PLA used for sum-of- products. 2-) Using the style of drawing in Figure 3.66 (see above), draw a picture of a PLA programmed to implement fl (x1, x2, x3) = m(1, 3, 4, 6). The PLA should have the inputs x1, x2, x3; the product terms P1, P2, P3, P4; and the outputs fl and f2. 20 3-) Show how the function f1 from problem 1 can be realized in a PLA of the type shown in Figure 3.65 (see below). Draw a picture of such a PLA programmed to implement fl. The PLA should have the inputs x1, x2, x3; the sum terms S1, S2, S3, S4; and the outputs fl and 2. wy www Figure 3.65.
