A question about noise modulation
It's high, for sure, but pretty linear vs level.
So what does this mean?
But in IMD graph, we see noise following level.Measuring dynamic range the standard way doesn't reveal this problem:
So noise must be going up with the amplitude of signal (noise modulation).
The high noise floor comes to surface in IMD distortion test relative to level:
It's high, for sure, but pretty linear vs level.
So what does this mean?
