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
