Feedback loop
From Wikipedia, the free encyclopedia
A feedback loop is a system where outputs are fed back into the system as inputs, increasing or decreasing effects — think of audio feedback from an amplifier. The term may refer to social effects; see cycle of poverty.
Often feedback and self-correction leads to adjustments varying with differences between actual output and desired output.
Feedback loops occur in countless phenomenona; a few follow:
- Audio feedback - the "howling" noise a guitar amplifier sometimes makes.
- Behavioral finance
- Creutzfeldt-Jakob disease
- Cycle of poverty
- Economics
- Electronic feedback loops
- Feedback
- Feedback amplifier
- Global Warming
- Hyperinflation
- Marketing
- Population dynamics
- Prostate cancer
The term is at times overused, difficult to define, and can be a buzzword.
