Although many sources of noise are well understood, the origin of the \"1/f\" or \"flicker\" noises remains, in general, a mystery in spite of their remarkably widespread occurance in nature. In this paper a review is given of the systems exhibiting I / f noise and the postulates researchers have made about its origin.","PeriodicalId":109521,"journal":{"name":"33rd Annual Symposium on Frequency Control","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132959779","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}
{"title":"Precision frequency control and selection: A bibliography","authors":"E. Gerber","doi":"10.1109/FREQ.1979.200371","DOIUrl":"https://doi.org/10.1109/FREQ.1979.200371","url":null,"abstract":"The bibliography covers the years 1968-1978. A total of over 3,000 references were found for this period using Science Abstracts A and B and studying the major journals, the Proceedings of the Frequency Control Symposium, sponsored by the US Army Electronic Research and Development Command. This bibliography, together with the index to the Proceedings of the Frequency Control Symposium, published in the Proceedings of 1976, should furnish a complete survey of the literature in this field. The attribute \"Precision\" in the title of this bibliography is restricting the contents to papers on those devices whose Q-value and frequency stability far exceed that of an ordinary LC circuit. Consequently, the reader will not find papers on ceramic resonators and ceramic filters listed in this bibliography. Material on polycrystalline and similar devices will only be included if it has some bearing on the behavior of high Q devices, for instance on the theory of vibration of anisotropic bodies. On the other hand, superconductive LC devices with their high Q are included in this bibliography. The main application of bulk wave monocrystalline devices lies in the area of frequency control and selection, whereas surface wave devices are being used in man~~ther fields. Therefore, papers on the fundamental properties of bulk wave devices are included to a fuller extent. As far as surface wave monocrystalline devices are concerned, only such papers are included which treat those aspects of their material and resonator properties which are considered pertinent for the application to precision control and selection. In the area of microwave frequency and time standards, obviously only references on gaseous masers are included. On the other hand, an excessive number of references may be found in the area of laser frequency standards. It is thought that, in this new and proving field, valuable information may be found in papers on gas lasers that are not directly concerned with frequency standards.","PeriodicalId":109521,"journal":{"name":"33rd Annual Symposium on Frequency Control","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126231220","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}
