The order of precedence is less well defined for logic circuits, like XOR or NAND, which are derived from the three basic circuits. It is best to use parenthesis to clarify the order of operations ...

But what if you don’t have a control-voltage keyboard sitting around or you want to combine all of the logic-based circuits that we’ve been building with other circuits under voltage control?

Overview of digital logic design. Implementation technologies, timing in combinational and sequential circuits, EDA tools, basic arithmetic units, introduction to simulation and synthesis using ...
