How can I build this circuit? (digitally)

Hi,

To make a circuit using logic gates from a truth table, there are two possible method. One is by Sum of Products and the other method can be by Products of Sums.

Here is an example for that: https://www.youtube.com/watch?v=cblZ7Rdaxog

To verify your truth table for the seven segment: http://img.photobucket.com/albums/v298/amerei1/ee/seven_segment_truth_table.png

From my experience in logic design, I still made my state diagram so that it would be clear what logic states I want to achieve. You can also do the same.

Hi everyone,

I am a total novice and I am attempting to teach myself. I'm required to design a circuit to take a binary input and display a number on a 7 segment display. I can only use AND, OR, NOT, NAND and NOR logic gates.

The numbers need to be displayed sequentially as follows; 1, 5, 6, 6, 9, 5, 5, 7

I need to use 3 sequencers or bit generators in the circuit as input.

I have uploaded my truth table. I really do not know if this is correct. At this point I am totally stuck and don't really know what to do. If the truth table is correct then I've managed to also obtain Boolean equations from it. However I still don't know how to build a circuit from this.

Any help would be hugely appreciated. Thanks for taking the time to read my query.

p.s. I am being directed to firstly construct a separate circuit for each segment from the truth table you have constructed. Then redraw the circuit to combine the separate circuits to form one complete circuit.

p.p.s I am eventually required to use a 3-to-8 decoder to simplify/reduce the number of logic gates
