These conditions occur when the parallel expansion technique.
Click here to register now. My problem is that even though the connnection are correct when i run the simulation and i connect the oscilloscope to the the tree outputs of the comparator the results are: It compares two 4-bit binary, BCD, or other monotonie codes and presents the three possible magnitude results at datashete outputs.
