COE 328 Chapter Notes - Chapter 2.1: Electric Light
Document Summary
The dominance of binary circuits in digital systems is a consequence of their simplicity, which results from constraining the signals to assume only two possible values. The simplest binary element is a switch that has two states. If a given switch is controlled by an input variable x, then we will say that the switch is open if x = 0 and closed if x = 1. Consider a simple application of a switch, where the switch turns a small lightbulb on or off. Consider now the possibility of using two switches to control the state of the light. Let x1 and x2 be the control inputs for these switches. The switches can be connected either in series or in parallel.
