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.
CMRR
That way they can filter noise (assumed to be common on both input terminals) and extract the signal even if it's relatively weak.
multimeter what does acv measure
It can measure micrometers which are really tiny

CMRR is common mode rejection ratio. it is the ratio of Differential gain to common mode gain. CMRR=Ad/Ac
pseudo
A high CMRR prevents the opamp from passing undesirable common mode signals.

CMRR stands for Common Mode Rejection Ratio, and it is a measure of how well the amplifier rejects signals that appear on both leads. The idea is that an amplifier should amplify the (Differential Mode) signal, but not any noise (Common Mode) that might appear on the lines, perhaps due to induction from nearby AC power sources. Since induction will show up on both leads, a high CMRR amplifier will have a greater signal to noise ratio overall
CMRR
Do you mean CMRR? If so, it means Common Mode Rejection Ratio. CMRR measures how well a differential input will reject a common mode signal (common mode means the same signal applied to both differential input leads at the same time). The ratio is expressed in decibels (dB).
You want an amplifier to reject common mode signals (the same signal applied to both inputs of a differential amplifier) because:it is generally noise, which sounds like staticit can cause drift in the amplifier eventually saturating it, causing clipping distortionBTW, single ended input amplifiers by definition have a CMRR of zero.
Quiescent power is defined as the amount of power consumed or required by an IC for its proper operation when there is no signal at the input.That is why we say Vin is zero at quiescent power.for example for 741C this power is 85mW.

I don't recognize CCMR.
