Title: Modification to get rid of power line noise and EMI
Post by: woody on December 16, 2016, 06:17:43 pm

Who would be interested in a mod that totally removes power line noise and 90% of all EMI over 500Khz? 

I have carried out some testing using ADC and DAC with digital filters, seems to work really well but have to sample at very high rates like 5-10 MSPS or it causes signal loss, it may be better to try notching in the time and frequency domain after the 4051
