If we arbitrarily set R1 = R2 = 10K and C1 = C2 = 0.01 µF and then use this derived transfer function, we calculate the following response. One nice thing about this circuit is that you can cascade ...
This sketch is for a zero offset, two pole lowpass filter that was described in part 1 of this series. It’s transfer function and algebraically-calculated roll-off results are nothing special. The ...
