Hello,
i decided to add an external analog Anti-Aliasing Filter at each input of the ADS1298.
The frequency spectrum which interests me is up to 150 Hz.
I want to use the oversampling of the delta-sigma ADC and sample the signal with 8kSPS, to reduce the filter order.
But what characteristics must the filter has, to reach good results?
Is it enough to use a first order filter?
regards,
Sebastian
