Feedback Systems
Feedback systems are processes that involve taking the output of a system and using it to make adjustments to that system. This concept is commonly found in various fields, such as biology, engineering, and economics. For example, in a thermostat, when the room temperature reaches a set point, the system receives feedback and turns off the heating. Feedback can be positive, enhancing a process (like population growth), or negative, stabilizing it (like maintaining body temperature). Essentially, feedback systems help regulate and improve functionality by continuously monitoring and responding to changes in the environment or system performance.

Feedback systems are processes where the output of a system influences its input in a loop, allowing for adjustments and improvements. Think of a thermostat in your home: it measures the temperature (output) and adjusts the heating or cooling (input) to maintain a desired level. There are two main types: positive feedback, which amplifies changes (like a microphone generating loud feedback), and negative feedback, which reduces changes to maintain balance (like your body regulating temperature). Feedback systems are crucial in many fields, including biology, engineering, and economics, helping to stabilize or enhance performance.
