Band-pass multiple resonance networks

The idea of "multiple resonance networks" is reviewed and extended to networks with the structure of bandpass LC ladders. This realization combines the properties of the previously described low-pass and high-pass realizations. It allows the generation, for example, of triple resonance networks with a transformer at one side and capacitive coupling at the other, overcoming the limitations in voltage gain of high-pass realizations. A simple transformation allows the generation of networks with single input and balanced output.
