0° and 180° filters.

Hello can anyone explain me 0° and 180° filter differences. I couldn't find too much information on the internet. I even don't understand is it phase difference between the filters or is it their own character. :lol:

It's just inverting the signal, a gain of -1.

If the filters are side-by-side (parallel), then the 0° setting has the two filters adding together. With the 180° setting, that signal is inverted, and in effect we subtract one signal from the other. That's what I think it is, anyway.

It probably doesn't matter with a the series connection... the second filter doesn't care, it just sees a signal coming in.
