i input finite-length signal periodogram function , power spectrum density. however, since signal has finite length, power spectrum density has sinc-like lobes. there implantation in scipy, can used de-couple sinc-like lobes can power spectrum density infinite version of finite-length signal?

i have used m2e plugin in luna 4.4.1 while handling dependencies , worked fine. normally, create new java projects convert them maven project. i decided wanted start using standard maven directory layout, recent project created maven project , added eclipse java facet eclipse treat java project. this has broken maven, no longer making it's dependencies available new projects. normally, eclipse adds "maven managed dependencies" library project maven dependencies; new projects no longer , dependencies never added project classpath. projects had been working before still add , remove them normally. i have narrowed problem down .classpath error; reason m2e has stopped modifying project classpath make it's dependencies available. can work around manually copying , pasting entries working project find way "re-automate" correctly. i have sidestepped issue buckling down learn gradle.
