Hello researchers,

I am researching the corrosion of reinforced concrete with coated rebar using electrochemical noise technique. In similar articles, a sampling rate of 0.5 Hz is mentioned. I would like to know on what basis the sampling rate is determined and what is the role of low-pass filters in this and how is its value determined? If the Potentiostat device does not have low-pass filters, what is the solution to eliminate aliasing?

Thank you
