  • \$\begingroup\$ In this case, the AND-plus-XOR circuit is NOT equivalent to the OR gate. Note the third input coming from C! \$\endgroup\$ – Dave Tweed Jun 2 at 19:49
  • \$\begingroup\$ @TomCarpenter make a truth table for the whole circuit or only for the OR gate? \$\endgroup\$ – R AND B Jun 2 at 20:05
  • \$\begingroup\$ The whole circuit. \$\endgroup\$ – Tom Carpenter Jun 2 at 21:53
