Design circuitry to run a seven-segment display for one digit. The input consists of a four-bit digit (where each bit is an input line). The outputs are a, b, c, ,,, and of the seven segment diagram light the segment, 0= do not light the segment). From a truth table, write and simplify seven Boolean expressions. Then draw the seven minimal circuits. Note: There are only ten rows of input in the table corresponding to the digits 0 ( 0000 two through 9 (1001two).
