Scosche ES004 10 Amp 100-Watt Single Stage Noise Filter

this is a 60 cycle hum nice neat continuous sine-wave it's actually a basic 60 cycle way with spurious other harmonics let me put my headset on the camera so you can hear with this so you hear what this is what you're looking at nitin here what you're seeing so and what we'll do next is I'll put the filter cable on and we'll take an hour look at this oscilloscope see what the difference is and they'll let you hear what the difference is I'll let you take a listen to it this is this is what the filter cable now connected you may hear me moving the headsets around a little bit but you do not hear the hum it's impossible to get rid of a 60 cycle hum but you can reduce the DB level maybe minus 20 minus 40 maybe approaching my 60 DB where it's not make a noticeable hum baby a mere whisper compared to what you're dealing with before okay in order to filter 60 Hertz and lower frequency out of
