What is a feedback loop? Input, processing time output Input influences output Output influences input Both B &C

## Step 1<br />A feedback loop in systems theory is a process where the outputs of a system are used as inputs to the same system. This means that the output of a system can influence the input of the same system.<br /><br />## Step 2<br />This concept is widely used in various fields such as engineering, biology, and information technology. In these fields, the output of a system can influence the input of a feedback loop.<br /><br />## Step 3<br />The feedback loop can be either positive or negative. In a positive feedback loop, the output amplifies the input, leading to an increase in the system's activity. In a negative feedback loop, the output reduces the input, leading to a decrease in the system's activity.
