The method involves generating an ac voltage synchronized to the displacement of a point on the resonator when it is vibrating. Another ac voltage is generated with a different frequency and is synchronized to the displacement of a point on the resonator when it is vibrating. The ratio of the vibrational frequency of the VRS to the difference or sum of the two ac frequencies is an integer. A voltage difference is established between forcer electrodes and one or more conducting regions of the resonator's surface. The voltage difference established is equal to the difference between the two ac voltages. |
