What is the effect of negative feedback in a noninverting amplifier?
Negative feedback in a noninverting amplifier results in improved stability and reduced drift.
How does negative feedback mechanism and positive feedback differ?
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.
What is current feedback shunt?
The effect of current shunt feedback in an amplifier is to The effect of current shunt feedback in an amplifier is to
What is the theory of voltage series feedback amplifier?
In a Voltage Shunt feedback Amplifier, the feedback signal voltage is given to base of transistor in shunt through a feedback resistor.This Shunt connection decreases the input input impedance and voltage feedback decreases the output impedance. In this amplifier input is current and output is voltage. Thus Transresistance is stabilized.Input and Output impedances are reduced by a factor of 'D'(desensitivity factor). Advantages: 1)Gain independent of device parameters. 2)Bandwidth increases. 3)Noise and non-Linear distortion decrease. 4)Prevents Loading effect. 5)Acts as good source for the next stage.
What is the effect of feed back on gain?
A: Number one it provide stability for the amplifier or system. The greater the feedback the greater the stability but less gain. In other words gain is inversely related to 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.
Is oxytocin an adenohypophyseal secretion?
no, it's release is the effect of a positive control feedback mechanism
What is a tuned rf jfet amplifier?
It's a junction gate field effect transistor that has it's bandwidth tuned to operate (amplify) in the radio frequency range.

How has the guitar pedals assisted with technology of the guitar and sound quality?
Guitar effect pedals were invented in the late 60's and more development into effects came in the 70's. The purpose of the effect pedal, namely the ever popular distortion, overdrive, feedback and delay pedals, was to eliminate the need to crack amplifier tubes and overdriving the feedback by proximity to the amplifier. Later, flanger, phaser and Hendrix's heavy use of the Wah-Wah effect became increasingly popular through sound shaping and dynamics. Most pedals are used do avoid amplifier and instrument abuse and damage. The sound dynamics from a pedal is designed to give the guitar the best effect based on varying conditions; loudness, regular amplifier distortion and feedback, the general acoustics of the venue, the amplifier cabinet type... the possibilities are limitless.
What is effect of an unbypassed resistor on the common emitter amplifier circuit?
An emitter resistor in a common emitter circuit will cause the stage to experience the effects of degenerative feedback if it is unbypassed. The degenerative feedback reduces gain. This is probably the primary effect in the described circuit.
How does a neuron create a positive feedback loop?
through what can be seen as the domino effect. when depolarization opens sodium ion channel and that results to the opening of more sodium ion channels. this creates a positive feedback loop.
