Either way very happy with the results and for the price these are a no brainer for unbalanced … WebNov 29, 2024 · After all, digital signaling offers strong noise rejection, so switching between levels is firm and there is plenty of built-in margin. Still, analog signaling is much more susceptible to noise. Put too much noise around an ADC and results suffer. And most analog noise problems trace back to one issue: a lack of attention to ground.
