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
What type of feedback is used in the phase shift oscillator circuit?
Positive feedback
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.
When you daisy chain two amplifiers how do you determine the combined output?
If one amplifier has its own feedback then that will be its gain witch can be added to the next amplifier gain. if both amplifier have a common feedback then that will be to total gain for both.
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 does positive feedback do in amplifiers?
It usually makes them self-oscillate or 'hoot'.
What has the author D J H Maclean written?
D. J. H. Maclean has written: 'Broadband feedback amplifiers' -- subject(s): Broadband amplifiers, Feedback amplifiers
Why positive feed amplifiers are called as regenerative?
The positive feed amplifiers are called regenerative because they increase the gain of the amplifiers.
What is frequency compensation?
Frequency compensation is a technique used in amplifiers. It basically controls the sound of the amplifier to make it sound clear and free of positive feedback.
What is negative feedback in an amplifier?
feedback that reduces gain to help stabilize amplifier operation. gain is easy and cheap to get, stability isn't. its a tradeoff. so amplifier is deliberately designed with much more gain than needed and negative feedback sacrifices some of that gain to stabilize it.
Is blood pressure negative or positive feedback?
Is the clotting of blood an example of positive or negative feedback?
What has the author Sol Rosenstark written?
Sol Rosenstark has written: 'Feedback amplifier principles' -- subject(s): Feedback amplifiers
Oxygen loading a positive of negative feedback process?
oxygen loading is a positive feedback response
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.
What type of feedback used in the oscillator circuit?
There are many different types of oscillator circuits, the majority of which use positive feedback.
