Hello, SMPS power supplies are known for higher noise versus ordinary
50Hz transformers. I was thinking that because of high frequency of
these power supplies, it should be easy to filter their output with a
simple low pass filter. for example a 1.0 Ohm and 100uF produce a filter
with f(-3db) ~1600Hz and it can drastically reduce ripples but for 50Hz
size of such capacitor is not practical. I like to hear of your thoughts.
