Abstract

Improvements in electromechanical filters made up of a plurality of flexural vibrating resonators and arranged in a filter structure, all the longitudinal axes of said resonators being arranged in parallel relation and coupled to each other by a coupling wire fixed to the average cross section of the same resonators, characterized in that a certain number of resonators are arranged on one side and others on the opposite side with respect to a rectilinear central coupling wire.
