Hello, this is not homework. I am working on a personal project and had I think a fairly simple set of questions. They really are all the same, so answering one as true probably means the others are true as well, but if not please point out where and how I'm wrong. I have a very basic idea of how logic gates may work but I need to know if I am correct: For an And gate: is the basic meaning that in order for the one right wire to output energy, both left wires must input energy? For an Or gate: to output, one of the left must input? For a Not gate: input from the left is 'stopped' and there is no output on the right? (and so the circuit may continue to an And gate with one that does have output and the And gate would then not output energy either?) For a Nand gate: Only if there is energy input from both on the left, there will be no energy output on the right? For a Nor gate: Only if there is no energy input on the left, there will be energy output on the right? For a Xor gate: Only if the input on the left differs from each other (one inputs, the other doesn't), there will be energy output on the right? For a Xnor gate: Only if the input on the left is the same for each (either both no energy, or both energy), there will be energy output on the right? I only need to know if I have the right idea, it doesn't matter weather 'energy' is not the right word, or if I need to have a source. Though I do need to know if what controls the circuit is that 'buttons' act as switches between going through no gate and going through a Not gate.
