What is the negative feedback of homeostasis?

Negative feedback loops occur in your body through its own internal controller for maintaining temperature, pH, hormone levels, blood sugar and other internal variable levels at homeostasis, which is the optimal internal state at which your body operates best.

Why do we need negative feedback?

The applied negative feedback can improve its performance (gain stability, linearity, frequency response, step response) and reduces sensitivity to parameter variations due to manufacturing or environment. Because of these advantages, many amplifiers and control systems use negative feedback.

What is the effect of negative feedback?

Feedback is the process by which a fraction of the output signal, either a voltage or a current, is used as an input. Negative feedback also has effects of reducing distortion, noise, sensitivity to external changes as well as improving system bandwidth and input and output impedances.
