An oscillator requires positive feedback to sustain oscillations by reinforcing the input signal and producing an output that is in-phase with the input. Positive feedback increases the overall gain of the system, allowing the circuit to overcome losses and maintain sustained oscillations without external stimuli.

Feedback is when the body reacts in the same direction as a stimulus. Negative Positive?
Feedback can be both negative and positive. Negative feedback occurs when the body's response counteracts the stimulus, helping to maintain homeostasis. Positive feedback amplifies the stimulus, leading to a larger response.
When the initial stimulus produces a response that reinforces the stimulus the mechanism is called?
positive feedback mechanism.
Compare and contrast negative and positive feedback mechanisms and give some examples?
Negative feedback mechanisms work to maintain homeostasis by reversing a change in a system, while positive feedback mechanisms amplify and reinforce a change. An example of negative feedback is the regulation of body temperature – if body temperature rises, mechanisms kick in to lower it; whereas in positive feedback, childbirth contractions become stronger and more frequent to facilitate delivery.
What is an example of positive feedback during sports?
An example of positive feedback during sports would be when a coach praises a soccer player for their accurate passing and encourages them to continue to make those precise passes. This positive reinforcement can boost the player's confidence and motivate them to improve their performance further.
Are positive feedback and negative feedback both components of homeostasis?
Yes, both positive and negative feedback are components of homeostasis. Negative feedback helps to maintain a stable internal environment by reversing any deviations from a set point, while positive feedback amplifies the response to a stimulus, often to achieve a specific outcome in the body. Both types of feedback work together to regulate physiological processes and maintain balance within the body.
Is blood pressure negative or positive feedback?
Is the clotting of blood an example of positive or negative feedback?
What is the difference between Positive feedback and Regenerative feedback?
positive feedback is always benificial but regenerative feedback may or may not.
Is contractions during childbirth positive or negative feedback?
Positive feedback.
Definition of negative feedback and positive feedback?
A: Any feedback that contributes to the input is positive feedback any feedback that subtract from the input is negative feedback
Tends to magnify a process or increase its output?
Positive feedback Positive feedback
How is a positive feedback stopped?
The positive feedback loop is terminated by the end of childbirth...
A blood clot stimulating the formation of more blood clotting is an example of?
Postive feedback
What is a positive feedback mechanism?
A positive feedback mechanism is a system the responds to perturbation in the same direction as the perturbation. A positive feedback mechanism allow cells to adapt to changes in their environment rapidly and efficiently. Positive feedback allows cells to reach new levels of equilibrium corresponding to the stimulus in the environment
In a feedback amplifier positive feedback produces an output that is?
In a feedback amplifier, positive feedback produces an output that is in-phase with the input signal. This can lead to instability and oscillation in the amplifier circuit. Positive feedback can increase the gain but at the risk of introducing noise and distortion.
What is the purpose of feelback how can you offer positive feedback?
What is the purpose of feelback how can you offer positive feedback
Can we use positive feedback in amplifiers?
Yes because an amplifier with positive feedback is an oscillator.
What type of feedback is used in the phase shift oscillator circuit?
Positive feedback
