What is a Digital Circuit?

What is a Digital Circuit?

• Defined by the interpretation of the signals (waveforms, if in time) in the circuit.
  Analog
  • Continuous Values
  • Fast, economical, low accuracy
  • Susceptible to noise & distortion DIGITAL
  • Discrete Levels
  • Accuracy related to cost (no. of "bits")
  • Less susceptible to noise
• Binary - 2 Levels or States
• Multi-valued - More than two Levels
