We all know that in the two negative-feedback circuit
It’s easy to figure out the Voltage-Gain (Signal Gain)
But here I see a terminology “Noise Gain” which is totally new for me
It says the Noise Gain of the two circuits is the same
Noise Gain= (R1+R2)/R1;
Here I got confused!!
What the Noise Gain is? What’s the definition of a noise gain?
How to calculate it…..
What’s the difference between Noise Gain & Signal Gain of an OP-circuit??
