Exercise 1 Segment display A 4-bit number, A, B, C, D (D is the most significant bit), is applied to the inputs of the decoder supplying the signals a, b, c, d, e, f and g that are used to drive a 7- segment display (see figure) generating numbers from 0 to 9. 1. Draw up the truth table for this decoder. A- BBCD-to-7-segment decoder C- D- (a) 134 2. Deduce and simplify the logic expressions for a and g. 3. Propose a logic circuit that can be used to realize the decoder. We will assume that the diodes of the display are controlled by low-level signals.
