I would like to calculate the component values for a Butterworth filter, but cannot seem to figure out how to apply the formulas to give me meaningful values.
I have read through a few books recommended, and they seem to all focus on the transfer function and how it related to amplitude over frequency, however, I would like to figure out how to calculate the values of each component to make this filter. I know of many calculators out there but for the purposes of this I prefer to do it by hand.
The specifications are just for a learning exercise but lets say we want a 4th order butterworth:
4 Pole
50Ohms impedance
146Mhz center frequency.
Can anyone point me in the right direction? I can't seem to figure out how to apply the formulas to get actual component values.
Thanks!
