Which is best positive feedback or negative feedback?
Obviously,it depends on the situation. consider a transistor amplifier.To minimize the change in collector current with respect to temperature,collector to base bias is used . This circuit uses a NEGATIVE FEEDBACK in order to compensate the rise in output current with temperature. But in order to achieve maximum gain, the same circuit can use POSITIVE FEEDBACK by connecting the amplified output to the input .
What type of feedback is used in the phase shift oscillator circuit?
Positive feedback
Can we use positive feedback in amplifiers?
Yes because an amplifier with positive feedback is an oscillator.
Why is negative feedback used in high gain amplifier?
A: Well for one thing if it is positive feedback the amplifier will saturate to one one side of the power buss or the other. An operational amplifier open loop gain can be 90Db which a tremendous gain so some negative feedback is necessary to reduce the gain and make the amplifier behave in the linear region for amplification
Explain current shunt negative feedback amplifier?
describe current-shunt negative feedback as applied to operational amplifiers, including derivations of the gain relation for each type of negative feedback.
Is blood pressure negative or positive feedback?
Is the clotting of blood an example of positive or negative feedback?
What is the definition of feedback factor?
the feedback factor is when you give something and get positive or negative feedback but in order t get this you have to lay something an (idea) to get "the feedback factor.
Is child birth negative feedback?
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.
Is urinating a negative feedback?
No it is positive feedback
Is contractions during childbirth positive or negative feedback?
Positive feedback.
Oxygen loading a positive of negative feedback process?
oxygen loading is a positive feedback response
Describing what is feedback system and differentiating between positive and negative feedback?
when a woman's contractions speed up during labor is negative or positive feedback
Are positive feedback and negative feedback both components of homeostasis?
No, negative feedback is the primary homeostatic mechanism regulating the endocrine system. Positive feedback is used much less frequently.
What are the two types of feedback mechanisms?
There are two types of feedback mechanisms: positive feedback, which amplifies processes, and negative feedback, which stabilizes systems. For More Information : agilityportal.io
Feedback is when the body reacts in the same direction as a stimulus. Negative Positive?
Your statement is for positive feedback.
When the body reacts to stop or work in the opposite direction of a stimulus is it known as negative feedback or positive feedback?
negative feedback
What are the example of negative and positive feedback in geography?
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.
