Can we use positive feedback in amplifiers?
Yes because an amplifier with positive feedback is an oscillator.
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.
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 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.
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
