Hello,There are tables as shown bellow representing coupling responce. each number is the even impedance coefficient for example for z1:
Z1_even=1.0183450=50.917 50=sqrt(Z1_oddZ1_even)
Z1_even=49.0995
I know that its similar to a filter responce.
is there a way maybe in matlab i could actually see this responce in a frequency plot from the impedances of the table?
I know its "butherworth filter" what could be done to treat this like a filter?
Thanks.

Hello Tesla23, in filter theory butterworth filters can be described using the following formula.
can i transform the gk formula of filters into multisection coupler response?
Thanks.
