An electromechanical filter comprising a plurality of parallel mounted mechanical resonators which are generally cylindrical in shape with a plurality of input and output resonators operating in a bending mode and at least one intermediate mechanical resonator operating in a torsional mode and being generally dumbbell shaped with two or more cylindrical portions connected by a torsion member and with electrostrictive transducer input and output members connected to the input and output resonators so as to provide filters having wide band characteristics. |
