 Sometimes it is cheaper to create circuits using only one sort of gate, and you might be asked to do so in the exam. These gates tend to be NAND & NOR gates. "But how can you create complex circuits by using only one type of gate?!" you may well ask. We'll now cover how other gates can be made from NAND & NOR gates:
