Question
Write the truth table and derive the expression for a,b,c,d,e,f, and g using four variable K-map.
In this Lab you are to design a BCD to Seven-segment display driver circuit that will take BCD number as input and display the corresponding decimal value of BCD input on a Seven-segment display, as shown in Figure 1. For undesired inputs (i.e. inputs from 1010 to 1111) the circuit will display U on the Seven-segment display. Each of the seven segments is labeled a through g. The numbers 0 through 9 light up the segments shown in Figure 2. For example, the number 0 lights up all but the middle segment, segment g. There are two types of 7-segment display available in the market. One is common anode and the other is common cathode. In DE2-115 board, the manufacturer used the common anode type display. To turn on a common anode display segment, you have to provide a low signal (0). For example, to turn on segment a, you have to provide a low signal (0) to the corresponding pin of segment a. 0 1 2 e 3 Figure 1. Seven-segment display a 4 5 6 Figure 2. Seven-segment display Function 7 8 9 To design your seven-segment display decoder, you will first write the truth table specifying the output values for each input combination. For example, when the input is ABCD = 0000, the outputs are abcdefg=0000001 and when the input is ABCD=1010 (undesired input), the outputs are abcdefg = 1000001 (display U).
