hello
a third order butterworth filter has two inductors in series and a capacitor in parallel, placed between the two inductors.
I thought that the second inductor would help filter out any remaining high frequencies. I spoke to someone who has a degree in electronics, he said the second inductor was there to match the first inductor and capacitor to the output of the circuit.
I didn't understand and he didn't have time to explain.
so if anyone would be kind enough to share that information I would appreciate it.
thank you
simon
