Hi guys
I need an advice to suppress my 12V charting noise on my motor bike. I’m not at all experienced in filter design.
I’m working on a project where the charting noise limit needs to be suppressed to maximum 200 mV PP.
As you can see on the pictures the MC has an extreme noise level (Chanel 1 - the yellow one). I have done a preliminary test with a basic 2nd order passive low pass filter (Chanel 2 - the blue one) and as you can see it is a bad approach.
What will you recommend my approach should be - A Murata fixed filter or design one like the Butterworth, Bessel or …
I hope one of you experienced guys can help
