Welcome, This is basically a even and odd BCD counter:- *If input 1 is high, the even counter is on, *If input 2 is high, the odd counter is on.
We can test it by making input 1 high and connecting 7-segment display to output, if the even count of BCD is shown, the logic circuit is cleadred the test .
