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

 Example of Digital Waveform representing digital

signals

1 0 0 1 0 1 1 0

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

False
