Abstract

A filter for electric signals has a substrate, a vibrating body capable of vibrating with at least two antipodes deflected in phase opposition relative to the substrate and has electrodes connected to a signal input and a signal output for electric excitation and for detection of the vibration of the vibrating body. The electrodes for detecting the vibration, each assigned to antipodes deflected in phase opposition, are connected to two separate terminals of the signal output.
