I am using octave/matlab to get the coefficient of numerator and denominator of a filter with filter command such as
I just want to learn how do you convert this coeffecient to the value of passive components of Inductors and Capacitors?
For example, a second order butterworth filter with cutoff frequency 1000 Hz sample at 3000 Hz with the following command gives the following
coefficients of numerator and denominator respectively,
[b,a]=butter(2,0.667); b=0.46554, 0.93108, 0.46554 a=1, 0.62147, 0.24069
How can we transform this into the value of passive inductors and capacitors?
