Hello Lynn,
Your understanding is correct but we don’t want to find the “Switching Transient”.
Just we want to pass same Noise along with information signal. Because output information signal we are connected to Circuit board by connecting 1st Order RC-Filter Circuit in between.
So, our Aim is Tune R& C values to protect my Circuit board. For that we want to know up to what level Noise is filtering.
We want to compare Filtered data with Reference voltage (i.e. 25mv) . If data is more than 25mv it means some data is not filtered. In this case we will change the R & C values.
