Dear all,
I am using P89V51RD2FBC ic for my application. I am sensing reed type limit switches as inputs to its I/O pins. As theses inputs as directly coming from the field side to input as controller i have connected LC filter in series with the input to controller to nullify the effect of any ac component. But i am unable to design the values of L and C for the same. Can any body help me with that.
Please give the guidance regarding design calculation for L and C ie which parameters would be helpful for me for getting L and C values.
regards
