using Taylor series expansion to the first order yields
where and denote the voltage gain, transconductance, cur-
rent gain, and transimpedance of voltage-controlled voltage sources,
voltage-controlled current sources, current-controlled current sources,
and current-controlled voltage sources, respectively.
It was shown in Chapter 3 that the weak form of the Tellegen's theo-
rem for periodically switched linear circuits is given by
Also, we showed that the network variable of a periodically time-
varying linear system can be written as
