Abstract

1. Filter circuit for blocking partial frequency ranges or allowing partial frequency ranges to pass, with at least two resonant circuit for each partial frequency range, characterized in that the resonant circuits are constructed and dimensioned in such a way that each component of each resonnant circuit at the same part of at least one further resonant circuit for another partial frequency range.
