Describe a negative feedback system?
Q: describe the negative- feedback system subject: Science A: To control the amount of hormones that are in your body, the endocrine system sends chemical messages back and forth within itself. This is called a negative- feedback system. example: it works much the way a thermostat works. when the temperature in a room drops below a set level, the thermostat signals the furnace to turn on. once the furnace has raised the temperature in the room to continue to stay off until the thermostat signals that the temperature system controls the level of glucose in your bloodstream. ur wlcm (: SnazzyChazzy <33
Can you describe how a negative feedback system works?
A negative F/B applies as applied to electronics systems meas that a portion of the output signal will be fed back to stabilize the system. It must be negative in nature so as to control the stability of the loop. If positive F/B is fed back then an uncontrollable situation will occurs whereby the system will oscillate uncontrollably As a rule the more negative F/B is applied the more stable the system. Also as a rule the more F/B the less gain is available to do work. So there is a trade off as stability increased the overall gain decreases.
Which part of a feedback mechanism causes change to make up for the departure from the set point?
The effector is the part of a feedback mechanism that causes change to make up for the departure from the set point. It receives signals from the control center and produces a response to bring the system back to its desired state.
What is the difference between oscillator and feedback amplifier?
There are two differences: a) the amount of feedback you allow b) whether you wire a frequency-determining device into the circuit First things first: ANY amplifier circuit that uses feedback, which these days is most of 'em because feedback improves the quality of an amp's output, will oscillate if there's enough feedback. This poses a real problem because the more feedback you use, the better the amp sounds. Your challenge, therefore, is to make an amp that uses not quite enough feedback to oscillate. The other is equally critical. If you want oscillation you usually want it on a specific frequency. You can build an LC tank or a crystal into the circuit to determine the output frequency if you're building an oscillator; if you're building an amp you wouldn't do this.
What is the use of electricity to communicate control and process information?
The use of electricity to control communication and process information is electro informatics. This branch of informatics deals with storage and retrieval of data through electricity.
Is a control mechanism that intensifies an earlier reaction A sensory receptor An effector Negative feedback Positive feedback?
sensory receptor
How does negative feedback control hormone levels?
you grow
What is an example of negative feedback mechanisms?
Control of blood pressure.
What is loop system?
A: It is any system where there is negative feedback to control its behavior
Which part of a negative feedback loop detects changing conditions?
The sensor component of a negative feedback loop detects changing conditions and sends signals to the control center for regulating responses to maintain homeostasis.
What is the self-regulating control mechanisms usually operate by a process called?
Self-regulating control mechanisms usually operate by a process called negative feedback. Negative feedback helps to maintain stability within a system by detecting changes in a controlled variable and activating mechanisms to counteract those changes. This helps to keep the system within a desired range or setpoint.
What is output feedback design?
A: A system ideally should have infinite gain but if that is so then it will saturate to one state or the other Feedback [negative] insure that will not happen the feedback will control the saturation making it stable.
How do you address negative feedback from your current job?
assume it is accurate and strive to solve the parts of the problems you can control and forget about the parts you cannot control.
What is a control mechanism that responds to a stimulus by decreasing its intensity called?
There are two kinds of feedback in the control of the body. Negative feedback occurs when a change happens in the body that makes the body beyond it's homeostatic level. Negative feedback reverses those changes and returns the body back to it's normal stage. Positive feedback occurs to temporarily amplify or enforce the change that is occurring. This process causes a number of increases until a signal is sent to the brain to stop the process.
What allows negative feedback to a control system?
Negative feedback in a control system allows for the system to self-regulate and maintain stability by comparing the output with a desired set point. If the output deviates from the set point, the negative feedback mechanism adjusts the input to bring the system back to the desired state. This helps the system to maintain consistent performance and minimize errors.
Why is temperature control is regarded as an example of a negative feedback?
Temperature control is an example of negative feedback because the body continually works to maintain a stable internal temperature. When body temperature rises, thermoreceptors signal the brain to trigger mechanisms such as sweating to cool down the body. Conversely, when body temperature drops, thermoreceptors signal for mechanisms like shivering to generate heat and raise the temperature. This feedback loop helps regulate the body's temperature within a narrow range.
What feedback control reduces variations away from a desired physiological state?
Negative feedback control mechanisms reduce variations away from a desired physiological state. This is achieved by sensing changes in the system, generating a response that counteracts the change, and bringing the system back into balance.
