Consider the BCD-to-seven-segment decoder discussed in conjunction with Figure. Suppose that the BCD data are represented by the logic variables B8, B4, B2, and B1. For example, the decimal number 7 is represented in BCD by the word 0111 in which the leftmost bit is B8 = 0, the second bit is B4 = 1, and so forth.
a. Find a logic circuit based on the product of max terms having output A that is high only if segment A of the display is to be on.
b. Repeat for segment B.
