Every Electronic System: Input, Process, Output, Feedback

However complicated an electronic product looks, it can always be broken into four stages:
1. Input: sensors or devices collect data from the environment.
2. Process: the system interprets that data and decides what to do.
3. Output: the system acts, by driving a motor, lighting a display or making a sound.
4. Feedback: the output is measured and fed back, so the system can correct itself.
This is the same model you met for mechanical systems in A3.3.2, with one addition: electronics can close the loop and watch their own output.

Note

Feedback is the stage that makes a system self-correcting rather than merely obedient.
Not every system has it, and that difference is developed fully in A3.4.10.

Input

What is put into a system

Sensors detect a physical change and convert it into an electrical signal the system can read.
A temperature sensor turns heat into a voltage, and a light sensor turns brightness into a voltage.
The individual input components are covered in A3.4.7.
