• Boolean algebra

  • logic circuits

    • a combinational logic (מעגל צירופי) is a device consisting of logic gates whose outputs at any time are determined by the current inputs
    • a sequential logic (מעגל סדרתי) is a device consisting of logic gates whose outputs at any time are determined by the current inputs and the previous state of the device
  • packaged building-block logic families can be divided into categories:

    • resistor-transistor logic (RTL) circuits are logic circuits built from resistors and transistors
    • diode-transistor logic (DTL)
    • transistor-transistor logic (TTL)
  • propagation delay
