Multiple feedback low-pass filter
WebIt also provides a simple single pole or two pole filter whose electrical response can be easily calculated. For a single pole low-pass filter, fc = 1/ (2 × π × RC) the filter roll-off is 6dB per octave or 20dB/decade. However, this filter does have some noticeable drawbacks: It is very sensitive to the component value tolerances.
