The following circuit is a simple active 2nd order hpf that I found online.
If I want to bypass the whole circuit, can I simply use a SPDT switch as shown? Using a DPDT for switching both input and output of the filter is not an option.
FWIW, I breadboarded it and I didn't notice any changes in noise when I bypass the hpf (and its input is floating) but maybe I'm missing something?
Any help is much appreciated as always!
