CONCLUSION Let us compare the method of solution presented above with the moreformal approach proposed by Bennett. The latter method leads to theexact steady-state transmission through a network containing periodi-cally operated switches. This method is perfectly general in that it doesnot require any assumption relative to the properties of the networknor to the ratio of t/T. As expected this generality implies a lot of de-tailed computations. In particular it rec^uires, for each reactance of thenet
