Hi all I have a quection on Scattering Parameters When we go for Complex design at high freq ( with complex transfer function) , does going for S parameters will be Helpful? When I have gone through a paper (by DR Howard Johnson, news letter), I read these S -paramaters are used for a Linear , Time Invariant Two Port Networks . and Also I read these are for modelling the connectors and cables . " Is this two port network in enough to model all the corresponding Poles and Zeros of a system at High Frequency ??"
