21. For a simple two-terminal device, the small signal equivalent circuit may be no more than two components. 22. The small signal equivalent circuit in terms of two-port parameters leads to the concept of dependent generators. 23. We'll use this fact in section 2.3 . 1 to design a lowpass FSS filter using equivalent circuits . 24. The magnetic field jump condition for the FSS mirrors the Kirchoff current division law for the equivalent circuit . 25. The vast scale of the topic of equivalent circuits is underscored in a story told by Sidney Darlington. 26. A network of impedances with more than two terminals cannot be reduced to a single impedance equivalent circuit . 27. The following table summarizes all the parameters to go from equivalent circuit parameters to expected reflection and transmission coeffecients. 28. Thus, the triggering scheme is the same as an SCR . The equivalent circuit is depicted in Figure 4. 29. Therefore, the equivalent circuit of the GMR structure consists of two parallel connections corresponding to each of the channels. 30. It must be remembered that this equivalent circuit is entirely notional and only valid for the small signal deviations.
