Introduction
Digital Signals
Digital waveforms can be used to represent digital
signals (e.g. 0 or 1, true or false), for example
• 0 (false) – represented by 0 Volts
• 1 (true) – represented by a small voltage, e.g. 3 Volts

Time
Digital signals are represented by a “high” state (1) or “true” state consisting of a small voltage
(e.g. 3V) and “low” state (0) or “false” state consisting of 0 Volts.
True True True True False False False False
