there are four types of feedback connetion. the one used is that which amplifies your input (Positive feedback).
voltage amplifier feedback current amplifier feedback transconductance feedback transresistance feedback
current series feedback amplifier=series parallel feedback amplifier or voltage to current amplifier,or TRANS CONDUCTANCE AMPLIFIER.
Yes, Amplifire have negative feedback.
neutralization is one of the methods to make the amplifier unilateral i.e. to remove internal feedback of the amplifier. It is done to obtain the maximum gain from an amplifier.
The effect of current shunt feedback in an amplifier is to The effect of current shunt feedback in an amplifier is to
voltage amplifier feedback current amplifier feedback transconductance feedback transresistance feedback
current series feedback amplifier=series parallel feedback amplifier or voltage to current amplifier,or TRANS CONDUCTANCE AMPLIFIER.
A: POSITIVE feedback will force the amplifier to sit at its rail saturated
A negative feedback amplifier (or more commonly known as feedback amplifier)can be defined as an amplifier which combines a fraction of the output with the input so that a negative feedback opposes the original signal.
in automatic volume contrrol
A: feedback is not an application but rather is a must to keep a system or amplifier stable in the linear regions
Yes, Amplifire have negative feedback.
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.
Negative feedback in a noninverting amplifier results in improved stability and reduced drift.
The input impedance of a current shunt feedback amplifier is the open loop impedance of the amplifier divided by 1+(A*beta)
positive feedback makes regeneration of the input signal,which creates more noise. ANSWER: To feedback positive voltage will do nothing for noise or any other reason but force the amplifier to saturate to the hi rial or the low rail of the power supply
