analog high pass filter > 8 poles

[FvM]

I do not necessarily need tchebycheff filter, I can use also other types, however, I was just hoping to see an implementation of a 10 poles (or more). I could not find any reference.

I conclude that you didn't check the references given in this thread.

Again, I am not convinced (as I also can read in other posts) that cascading gives the wanted result.

Most active filters with > 2nd order consist of cascaded second order blocks. The filter coefficients are however specific for the designer filter prototype and total order. There are practical limits of useful order but 10 to 16 should work.

ok... I think I need some time to digest this! Thanks to all of you for the many contributions. Much appreciated.
