  8. Abstract : since piezoelectric resonant filter can not effectively prohibit higher - frequency harmonic, the mechanism of this problem has been discussed by means of a specific example which shows that there exists lots of undesirable resonant frequencies of piezoelectric that would let pass undesirable signals. to solve this problem ， an ameliorated electrostatic mechanical resonant filter is proposed and a specific case is demonstrated. the example of electrostatic resonant micro - bridge asserts that by adjusting the gap of exciting capacitance the higher - frequency vibrating model of micro - bridge cannot be excited based on orthogonal character of intrinsic vibrating shape of micro - bridge, so that this kind of resonant filter can effectively filter out undesirable higher - frequency harmonic
