Grounding
In many circuits, a zero reference point is shown connected to earth, or grounded.
In this circuit, the point Y has been connected to ground, and is at 0 V. Therefore point X could be...
Logic gates are at the heart of digital electronics. In digital electronics, we need to know nothing about electricity, other than the difference between on (1) and off (0).

Electronic systems consist of:
· An input device to sense changes, e.g. a light detector
· A processor that responds to the change
· An output device that enables the system to do something useful.
· There may...
