P7 51 Consider the BCD to seven segment decoder discussed in conjunction with Figure 7 26 on page 380 Suppose that the BCD data are represented by the logic variables B 8 B4 B2 and B 1 For example the decimal number 7 is represented in BCD by the word 0111 in which the leftmost bit is B 8 0 the second bit is B 4 1 and so forth a Find a logic circuit based on the product of maxterms having output A that is high only if segment A of the display is to be on b Repeat for segment B
