WebA digital compensation filter for acceleration-induced effects is designed on the basis of this model. Experimental results explain that the acceleration-induced effects of the pressure sensor were less than 11% after using the digital compensation filter. A series of test data verify the accuracy, reliability, and generality of the model. http://www.rfcafe.com/references/radio-news/super-selectivity-crystals-july-1957-radio-tv-news.htm
