I am facing a noise problem when reading the ADC from Matlab Simulink using the F28937D board. I have tried to mitigate the noise by adding capacitors in parallel to the ADC input, but these capacitors cause a phase shift in my AC current reading signals, which is not acceptable. I would like to know if there is any alternative solution to address this noise problem. I appreciate any suggestions or advice. Additionally, if the only viable solution is the use of digital and analog passive filters, I would like this.
Thaks a lot
