Digital Logic Circuits (DLC) Practice Test — Flashcards

A Digital Logic Circuits (DLC) uses digital inputs to make logical decisions and produce digital outputs. Every logic circuit requires at least one input, before it can produce any kind of output. Digital logic inputs and outputs are usually binary - there can only be one of two possible values.

There are two basic types of logic circuitry: combinational circuitry and state circuitry.
Combinational circuitry behaves like a simple function. The output of combinational circuitry depends only on the current values of its input.
State circuitry behaves more like an object method.

All digital systems can be constructed by only three basic logic gates. These basic gates are called the AND gate, the OR gate, and the NOT gate. Some Computer textbooks also include the NAND gate, the NOR gate and the EOR gate as the members of the family of basic logic gates.
