A: An amplifier operates withing its open loop response a negative feedback insure that the amplifier remains in its linear region. therefore reducing effects of saturation, storage time to name a few.

Is thermoregulation in humans regulated through positive or negative feedback systems?
Thermoregulation relies on negative feedback. Negative feedback works to return a system to homeostasis by reducing a stimulus, such as a change in temperature. By contrast, positive feedback systems amplify or speed up a response.
Why S block elements are powerful reducing agents?
because they have high negative values of electrode potential.
What is the advantage of the Hubble Space Telescope over a ground based telescope?
One major advantage is that it does not have to contend with the distortion of light caused by the atmosphere.
Is Cellobiose is reducing or non reducing sugar?
It's a reducing sugar.
Is maltose non reducing sugar?
maltose is a reducing sugar ..
In a common emitter transistor the primary purpose of a resistor connected to the emitter is to?
The emitter resistor in a common emitter configuration provides negative feedback to the transistor, reducing both its voltage gain and distortion.

What are the effects of negative feedback?
1. less nonlinear distortion, 2. reduction in gain, which is actually in our control 3. since product of bandwidth and gain is constant, reducing gain gives higher bandwidth. 4. more gain stability, as for high gain values, stability is dependent on feedback factor, whic is in our control. 5. can be used to make voltage controlled voltage source, C cntrolled V sources, V controlled C sources and C controlled C sources

What is the use of feedback in amplifiers?
A differential amplifier amplifies the difference signal between its two inputs, while rejecting the common mode signal that might be present relative to circuit ground. Operational amplifiers are great for this purpose. With a sufficiently high open loop gain, the Comon Mode Rejection Ratio (CMRR) is excellent. This is done to reject the common mode voltage that is developed in the signal cable, a twisted-pair cable, often caused by noise or AC current in the vicinity of the cable run. Applications include differential microphones, reducing hum, or small signal sensor monitors, often over a large distance such as in a process control application. The differential amplifier is also much easier to setup for a specific gain, as well as to setup for a particular frequency response, because its input impedance is so high, and because its bridge mode operation is very easy to use.
What is a bit crusher?
A bit crusher is a lo-fi digital audio effect which produces a distortion by reducing the resolution or bandwith of the audio data.
What is the best way to stop feedback in live sound?
You can ensure that the speakers are not too close to microphones and you can ensure that the pickup from the mics is not too great. If the microphone pickup is very sensitive this may cause more feedback, reducing this and using your mixer and amp to increase the volume is a good idea. If you are using stage monitors, try reducing the volume of these or implementing a feedback destroyer for those channels which the monitors are on.
Attenuators are the opposite of a what?
An attenuator is the opposite of an amplifier. An attenuator is used for reducing the power of a signal. An attenuator is able to do this without modifying the waveform of the signal.
Can general reserve be negative?
Yes it can. If it is negative it means the business has a cumulative loss. It has the effect of reducing the owners' funds in the balance sheet.
What has the author William N Smott written?
William N. Smott has written: 'Sampling and coding as a means of reducing time and amplitude distortion in recording' -- subject(s): Electronics
What does a negative Benedicts test indicate?
A negative Benedict's test would indicate that there isn't any presence of reducing sugars in that particular substance.
What are aggravating and mitigating circumstances?
Increasing negative = Aggravating. Reducing negative= mitigating. Aggravating circumstance is a circumstance that does not exonerate a person but which reduces the penalty associated with the offense.
