GinnyAnswer

Final answer:

Signal circuits are crucial inputs for control modules/components in digital circuits, operating with fixed voltage levels for logic states.


Explanation:

Signal circuits serve as input to a control module/component and can have fixed-level, variable, or digital voltage. In digital circuits, two main voltage values are used to represent logic states: a logic high (VDD to VOH) and logic low (VoL to GND). Integrated circuits contain transistors that handle digital signals in binary code, switching between fixed voltage values.
