Hi There
I’m new at this forum.
I’m not at all familiar with digital low pass filters.
I was taking a look to the EmonLib and regarding the following code snippet I would like to ask some question about it:
offsetI = offsetI + ((sampleI-offsetI)/1024);
filteredI = sampleI - offsetI;
I know that this is a Low pass filter to remove the DC bias from the I samples, but I cannot associate
each equation term with the low pas filter’s corresponding ones.
I would appreciate some help on that.
Thank you very much.
