Question

7-segment 4, display7 decoder S Figure 3.7-segment display decoder To design your seven-segment display decoder, you will first write the truth table specifying the output values for each input combination. We have started the truth table for you in Table 1. For example, when the input is Dio 0000, all of the segments except g should be on. Because the outputs are active low, they must be Sga 1000000. Complete the truth table for the 7-segment display decoder circuit. You will need to turn in your completed truth table. The seven-segment display uses active-low signals, meaning that 0 turns the segment ON and 1 turns it OFF. You will need to flip the polarity of your outputs to compensate Hexadecimal Inputs Outputs 40 4 Table 1. Truth table for 7-segment display decoder


after completing the truth table, write equations for each output segment. ( through Sa-Sg so 7 equations) using k-maps

next translate your equations into logic gates using only ONE design for all the equations.
