Why a occilator requires positive feedback?
A: How else can it sustain oscillation. If the feedback dies so does the oscillation it must have a continuous positive input.
A: Any feedback that contributes to the input is positive feedback any feedback that subtract from the input is negative feedback
positive feedback is always benificial but regenerative feedback may or may not.
Positive feedback increases a process and negative feedback decreases a process. An example of positive feedback is uterine contractions during labor. The positive feedback mechanism works to keep increasing the contractions until delivery is complete.
A: POSITIVE feedback will force the amplifier to sit at its rail saturated
In Amplifier if feedback is occures when the feedback signals is in phase with the input signal the feedback is known as Positive feedback. And the feedback is occures when the feedback signals is out of phase with the input signal the feedback is known as negative feedback.
Positive Feedback--It reinforces the stimuli
Positive feedback Positive feedback
Negative feedback is a means to keep amplifiers and systems in a linear region, Positive feedback is a means to force a circuit to become unstable. usually oscillators have either positive phase or level feedback to make them unstable to oscillate.
Positive is good negative is bad
The positive feedback loop is terminated by the end of childbirth...
Yes because an amplifier with positive feedback is an oscillator.
Negative feedback reverses a controlled condition back to its homeostatic state. A positive feedback accelerates or makes a action more powerful.
Oxytocin is regulated by positive feedback under certain circumstances. During childbirth, a positive feedback loop regulates its secretion.
A boiler is an example of a positive feedback system!
positive feedback is when the response by the recipient has responded in a good impression?
oxygen loading is a positive feedback response
Is this sentence grammatically correct It would be very kindly if you can leave a positive feedback?
it would be kind if you could leave a positive feedback Or, It would be kind of you to leave positive feedback. Perhaps better: I would be grateful if you leave your honest feedback.
the types of feedback are positive and negative feedback
In positive feedback, the system moves the variable further and further away from the set point of the variable. In negative feedback, the system moves the variable back to the set point. Another answer Negative feedback will stabilize an amplifier. Positive feedback will force an amplifier into an unstable state. This holds true for any other system too. Another Answer Negative feedback subtracts a portion of the output from the input signal. Positive feedback adds… Read More
When the positive differential input terminal of an OP AMP is linked to the output, we have positive feedback and when the negative differential input terminal is linked to the output , we have negative feedback.
when a woman's contractions speed up during labor is negative or positive feedback
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
positive feedback mechanisms
In a positive feedback system, the output increases the input.
An amplifier becomes an oscillator when positive feedback is applied. It is the simple way to do it.
Is the clotting of blood an example of positive or negative feedback?
Your statement is for positive feedback.
A negative feedback would be if the planet heats up, the glaciers will melt, lowering the albedo effect of the snow, and in turn causing the planet to heat up more That is positive feedback, not negative. Positive feedback enhances the initial stimulus, negative feedback reverses the initial stimulus. The planet starts by heating up, then heats up even more, which is positive feedback.
a goal going in in football . the player watches the ball go in the net and that is seen as positive feedback Whats sort of answer is this???????????????? This answer means that by seeing the goal go in the player receives internal postivie feedback, they know what they have done is a ggod thing so they fell a sense achievement. This is positive feedback. Not external positive feedback like normal positive feedback, that is… Read More
they are positive feedback and increase activity negative feedback.
Here's a hint: positive feedback tends to break the system. Therefore, if there is regulation, there is a negative feedback loop.
Positive feedback speeds up reactions and negative feedback slows them down. In electronics and control systems, positive feedback means the feedback gets added to the input and then goes as output. And negative feedback means that the output is input minus feedback (from output). This is the most basic and layman answer I can think of. In social and business terms, a positive feedback means a good response ( a praise for a product, or… Read More
False. This is what negative feedback does, not positive. So the answer is false.
After someone does something they receive feedback from other people regarding their performance. Positive feedback may include praise, rewards, or recognition within their group.
Positive feedback as applied to closed loop control systems is when the closed loop gain is positive.
Perhaps you don't understand the meaning of positive and negative feedback. Positive feedback keeps adding to a process. Negative feedback doesn't. If a person fills a bathtub, positive feedback will continue the filling even if it runs over. Negative feedback will turn the water off when the tub is filled. So, negative feedback maintains homeostasis. Homeostasis means "steady state". When a processes is completed, it turns it off. Example: Blood sugar levels remain in a… Read More
A negative feedback will stabilize an amplifiers positive feed back will force the amplifier to either saturated state. this will hold true for a system too. A more general answer follows. 1. Feedback: Getting information about what just happened and responding to it. 2. Negative Feedback: The response lessens the output. 3. Positive Feedback: The response increases the output.
Thank you for writing. I appreciate your feedback and your perspective.
That's negative feedback. Positive feedback ruins homeostasis.
There are two main types of feedback: negative feedback which will return the system back to the normal level or positive feedback where the process will add until an end point is reach. Most reactions in the body are negative feedback but the best example of a positive feedback is blood clotting.
the delivery of a baby is positive feedback if you have done it well. This is because people will tell you how you have done and they will tell you the positive and negative things about the process.
there are four types of feedback connetion. the one used is that which amplifies your input (Positive feedback).
Negative feedback since positive feedback adds to it.
In negative feedback systems, the response reverses a change in a controlled condition, and in positive feedback systems, the response strengthens the change in a controlled condition.
No, negative feedback is the primary homeostatic mechanism regulating the endocrine system. Positive feedback is used much less frequently.
