  • Volt-Ampere / Watts
  • Analog vs Digital
    • The word analogue is used to reflect the concept when some physical phenomenon is converted into its electric signal analogue.
    • As physical phenomenons tend to not be discrete, electric circuits analogue with real world can not be discrete either. Therefore analog signals are continuous.
    • The word digital is used when a phenomenon properties are coded, then decoded.
    • You can ‘digitize’ anything by coming up a criteria or a threshold to classify states to either ‘1’s or ‘0’s.
  • Simple circuit concepts:
