Four of these techniques are illustrated by some of the papers in this issue. One of the most fruitful of these is in the field of statistics, and in particular its application to nonlinear systems. R. C. Booton presents a paper which derives the cross-power density spectrum for a component with saturation or clipping. From this cross-power operator one can determine the quantity of output signal which is correlated with the input, the amount of harmonic distortion power present in the output, and an equivalent \"gain\" term satisfactory for use in testing for the build-up of periodic oscillations.","PeriodicalId":232856,"journal":{"name":"IRE Transactions on Circuit Theory","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1954-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115639170","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}

An amplitude-sensitive (or zero-memory) nonlinearity is interpreted as being approximately equivalent to a linear frequency-insensitive device, and a formula is derived for its equivalent gain. A simple rate-limited control system with a Gaussian input is analyzed as a specific application. Approximation of a general nonlinear element (containing memory) is considered next, and a relation between equivalent-system impulse response and the response of the actual nonlinearity is derived.","PeriodicalId":232856,"journal":{"name":"IRE Transactions on Circuit Theory","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1954-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117345441","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}
