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.
