Datasheet Clarification around Baseline Reset

[jacintal]

Hi,

The following is our understanding of the PSoC 6 datasheet, could anyone check if this is correct?

If Sensor Auto-Reset is enabled, the baseline follows the raw count

If Sensor Auto-Reset is disabled, the baseline will/will not reset depending on the following conditions:

1. For Noise threshold:
   1. If the baseline < raw count < (baseline + noise threshold), the baseline will reset with the raw count.
   2. If raw count > (baseline +noise threshold), the baseline will not reset.
2. For Negative Noise threshold and low baseline reset:
   1. If (baseline - negative noise threshold) < raw count < baseline, the baseline will reset with the raw count.
   2. If Raw count < (baseline - negative noise threshold) for a number of samples more than the low baseline reset, the baseline will reset with the raw count.
   3. If Raw count < (baseline - negative noise threshold) for a number of samples less than the low baseline reset, the baseline will not reset.

On top of that, I was wondering if the Noise threshold and Negative Noise threshold are in terms of percentage of the baseline or an absolute number.

Thank you in advance for your help. Have a great day!

Hi @jacintal ,

Your understanding is right and for the Software threshold parameters we calculate them as a percentage of the signal:
