This network effect follows a statistical power law in the idealized case, though negative feedback can occur (through rising local costs).

Positive feedback can also occur in other forms of cell signaling, such as enzyme kinetics or metabolic pathways.

Negative feedback occurs when the result of a process influences the operation of the process itself in such a way as to reduce changes.

If you have access to an equalizer, dampen the frequencies where feedback is occurring.

Negative feedback occurs when the output of a system acts to oppose changes to the input of a system.

Once feedback occurs, the technician uses the graphic equalizer to reduce the gain on the appropriate band (or frequency).

Sometimes a feedback (or a reaction) does not occur immediately - the process contains delays.

When feedback occurs, it results in a disturbingly loud tonal signal.

The sound engineer can increase the level of a microphone or guitar pickup until feedback occurs.

Feedforward and feedback often occur in one and the same system.
