Abstract
Изобретение относитс к измерительной технике. Цель изобретени - расширение частотного диапазона за счет компенсации резонанса при сохранении динамического диапазона. Сигнал дл пьезоэлектрического вибропреобразовател 1 поступает на вход усилител 2 зар да, а затем на вход блока 9 компенсации, где фильтр с частотой, соответствующей резонансу пьезоэлектрического вибропреобразовател 1. компенсирует увеличение сигнала на резонансе. 3 ил.The invention relates to a measurement technique. The purpose of the invention is to expand the frequency range by compensating for the resonance while maintaining the dynamic range. The signal for the piezoelectric vibration transducer 1 is fed to the input of the charge amplifier 2, and then to the input of the compensation unit 9, where a filter with a frequency corresponding to the resonance of the piezoelectric vibration transducer 1. compensates for the increase in the signal at the resonance. 3 ill.
