Hello all,
what are the switches in this circuit? it look like its just there to cut out the noise rejection part of the circuit when the frequency is higher, but what would the reason forthat be? does the noise rejection part affect anything if a clean higher signal freq is coming in? and if i was going to build this to use for low freq could i just omit the switch and have the noise rejection permanently in place?
