Is there formula to calculate error related to power system frequency, sampling frequency and OSR
e.g.
EMDC Version: Energy Measurement Design Center version 1_30_00_00
Power system frequency: 60 Hz
Sampling Frequency (Hz): 4096
Oversampling Rate (OSR): 256
Hello,
Oversampling helps reduce the thermal noise seen in the ADC readings, which effectively improves ENOB (this is because the SNR value improves). There are many documents so I'll share a couple if you want to learn more. For the formula, there is something similar in our Oversampling the ADC12 for Higher Resolution section 2.2.
There aren't any software APIs in the EMDC for getting the error or noise as these are also dependent on hardware layout and component selection.
