SISO (single-input single-output)

SISO, or Single-Input Single-Output, refers to a system where one input leads to one output. It’s a common concept in engineering and control systems, where you might think of it like a simple light switch. The switch (input) controls one light bulb (output). If you flip the switch, the bulb turns on or off. This model helps analyze and design systems by focusing on the direct relationship between one cause and one effect, making it easier to understand and predict how systems behave.
