Since the frequency of an RC filter is =3D 1/(2piRC), and is affected by th=
e
value of R:

1. Wouldn't the frequency response of the filter change based on the signal
source impedance? (Since R would be in series with the source signal)

2. I ask because I was thinking of placing a current limiting resistor afte=
r
the opamp output but then noticed that it would be in series with the high
pass filter's R, changing the effective R value and therefore changing the
frequency response of the filter.
