ELECTRO MECHANICAL FILTER |
摘要 |
The electromechanical filter for e.g. a channel filter in a carrier wave system consits of axially parallel flexural resonators fixed to a base plate and mechanically coupled by wires. The end resonators have piezoelectric transducers. The two peizoelectric transducer plates (3a, 3b) have different dimensions and/or are made of different materials. The advantage lies in avoiding unwanted resonance in a simple and cheap manner. |
