A3.4.8 Output devices and signal conversion Key Definitions

Definition

Output

What comes out of a system

Definition

Signal Conditioning

The processing of an analogue signal to prepare it for the next stage, such as filtering, amplifying, or converting it for use in a digital system.

Definition

Signal Conversion

The process of transforming a signal from one form to another (e.g., analogue to digital), allowing different components to communicate or process data correctly.
