DOUBLE-BAND ELECTROMECHANICAL FILTER,
Abstract
The Author Certificate presents an electromechanical double band filter in the form of interconnected cylindrical resonators. The first and last resonators are connected respectively to two pairs of magnetostriction transducers which are tuned in pairs to the midfrequencies of the first and second pass bands of the filter. To obtain an arbitrary separation of midfrequencies of the filter pass bands with any ratio of one pass band width to that of the second, all the resonators are interconnected in parallel. Torsional vibration transducers are used as the input and output transducers, tuned to the midfrequency of the first pass band. These transducers are connected to the input and output resonators near their ends, at points where the resistances of the resonators operating in the torsional vibration mode tend to infinity. Bending vibration transducers are used as the input and output transducers tuned to the midfrequency of the second pass band. These transducers are connected to the middle of the input and output resonators at points where the resistances of the resonators operating in the bending vibration mode tend to infinity. (Author)
