QUESTION 3 (a) Write the truth table for a 4-bit gray to binary code converter in Figure 3 (i). G3 G2 B2 G, B, Go Figure 3 (i) (b) A gray code to 7-segment display decoder in Figure 3 (i) is to be designed. The input is the gray code and the outputs (a to f) are connected to common-anode 7- segment display. The display will show the number of the Gray code that is equivalent to its BCD number. Gray to 7-segment display decoder a G3 b b. G2 GI Go f d Figure 3 (i) (i) Write the truth-table for this decoder. (ii) Obtain the minimized SOP expression for output a.
