Instrumentation amplifiers are designed to reject common-mode noise, which is noise that appears equally on both input signals. However, they cannot reject differential noise, which is noise that affects one input signal differently than the other. Additionally, any noise that is outside the common-mode rejection ratio (CMRR) capabilities of the amplifier may also not be effectively rejected. Therefore, high-frequency or specific types of interference can still impact the output.

What is an Ideal Op Amp?
One that is not affected by noise and doesn't vary.
In an amp What is better high or low signal to noise ratio?
Signal to noise ratio is the difference between the noise floor and the reference level.
Why instrumentation amplifier is a good differential amplifier?
An instrumentation amplifier is a good differential amplifier because it offers high input impedance, which minimizes the loading effect on the signal source, and low output impedance, ensuring efficient signal transfer to subsequent stages. Its three-op-amp configuration enhances common-mode rejection, allowing it to effectively reject noise and interference while amplifying the differential signal. Additionally, it provides excellent gain accuracy and stability, making it ideal for precision measurements in applications such as medical instrumentation and sensor signal processing.
What is the advantage of using external compensation for an op amp?
because it helps in noise reduction,bandwidth maximization
What is the idel op-amp CMRR?
A: Most op amp feature a 90 Db noise ratio rejection. For a 741c it varies from 70 to 90 Db ideally the bigger the number the better.
What is a difference between an operational amplifier and instrumentation amplifier and can you use one opamp to perform a same task as 3 opamp instrumentation amplifier?
An op amp is made from transistors, resistors and capacitors. It is enclosed in a "chip". A basic instrumentation amp is made of 2 op-amps. you can't have a single op-amp perform as good as a instrumentation amp, although it can perfrom the same task. An i-amp has much better CMMR (common-mode rejection) and a higher input impedance.
Difference between instrumentation and operational amplifiers?
An instrumentation amplifier is made out of 2 or 3 operational amplifiers.
Why is my amp making a buzzing noise?
Your amp may be making a buzzing noise due to a grounding issue, a problem with the power supply, a faulty cable, or interference from other electronic devices.

How do you stop a realistic sa-10 amp from making a humming noise?
Unplug it.
What is the input to the op-amp used in the room noise detector circuit?
microphone
Why does the amp make noise when you get too close?
It's called feedback. The microphone causes a loop, what is coming out if the amp is being asorbed by the mic, sent back to the amp and projected again. The loop causes a squeal.
Do brass cymbals on an electric kit make noise without an amp?
No. Well, not if they are ASL Revolutions.
Why does the amp ground wire make noise?
IT MAY NOT HAVE A CHOKE BUILT INTO THE CIRCUITRY. YOU CAN BUY A NOISE SUPPRESSOR AT RADIO SHACK. THIS SHOULD ELIMINATE MUCH OF THE ALTERNATOR WHINE NOISE. GOOD LUCK! ...BB
99 gmc Yukon Denali factory amp diagram?
Bypass it, you will have engine noise if you try to intigrate with it.
