What to Focus On

  • Discrete circuits use separate components connected by wires.
  • Integrated circuits place many components on a single chip.
  • ICs are classified as monolithic, film, hybrid, and multichip.

  • Analogue signals vary continuously.
  • Digital signals have only two levels: 0 and 1.
  • Digital signals use binary representation.

  • Logic gates are building blocks of digital circuits.
  • There are three basic gates: OR, AND, and NOT.
  • Boolean algebra uses only two values: 1 and 0.

Common Mistakes to Avoid

An OR gate gives output 1 only when both inputs are 1.

An AND gate gives output 1 when at least one input is 1.

The NOT gate can be built using diodes just like OR and AND gates.
