For 5.6uF in 6db/octave, high pass would be at 7000Hz
For 0.22mH in 6db/octave, low pass would be at around 2900Hz
Wonder is there a calculation to determine what is the xover value if i put a cap with 5.6uF, and parallel with a coil of 0.22mH, in a 12db/octave butterworth network?
The filter is unlikely to have a Butterworth response but it will be 12dB/octave. Butterworth (or any other alignment) requires a specific ratio between the two parts.
As for the results - easiest and best is just to simulate it.
