Thanks to the progress of digital electronics, new time-interval analyzers have been made available in the last few years. Such instruments measure the time stamp of the input events at high sampling speed (MS/s), and with high resolution (10-100 ps). We propose the linear regression as a means to estimate the frequency from time stamps of the input signal. The frequency counter based on the linear regression is called Ω counter. The linear regression is interpreted as a finite impulse response filter which takes the frequency samples as the input, and delivers the estimated frequency at the output. We derive the transfer function of such filter, which turns out to be parabolic shaped. As compared to the H and Λ counters, the Ω counter features better rejection of the background noise. We define the quadratic variance (QVAR), a wavelet variance similar to the Allan variance, and we derive its statistical properties. The QVAR is superior to the AVAR and MVAR in the rejection of the background noise.","PeriodicalId":57667,"journal":{"name":"时间频率公报","volume":"56 S1","pages":"338-342"},"PeriodicalIF":0.0,"publicationDate":"2015-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1109/FCS.2015.7138854","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72536401","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The structural symmetry of the resonator and mount combination has been shown in past work, both theoretical and practical, to have a strong influence on acceleration sensitivity, and specialized structures have been developed [1], [2], [3] that have greatly improved performance. However, with applications such as airborne radar systems, there is a persistent demand for further improvement. The design of many of the practical high-stability resonator products that have a need for good acceleration sensitivity is also constrained by other attributes, such as high quality factor, and these constraints typically result in a low-frequency overtone device with a fully contoured resonator element design. In this paper, the effect of the concentricity of the contour shape on the quartz disk in contoured resonators is considered, and results are presented that demonstrate a strong correlation between the contour offset from the blank center and the acceleration sensitivity of the resonator. Methods are also described for measurement of the contour position relative to the perimeter of the disk.","PeriodicalId":57667,"journal":{"name":"时间频率公报","volume":"25 1","pages":"427-431"},"PeriodicalIF":0.0,"publicationDate":"2015-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75712807","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
