What Are Positive Feedback Loops
Positive and Negative Feedback Loops in Biology - Albert.io
A feedback loop is a biological occurrence where the output of a system amplifies the system (positive feedback) or inhibits the system (negative feedback).
Positive feedback tends to cause system instability. When the loop gain is positive and above 1, there will typically be exponential growth, increasing ...
