Find best Spectral Estimation Method for a Power Spectral Density plot. A menu of 10+ spectral estimators from Steve Kay's textbook 'Modern Spectral Estimation' 1988 is available to choose from. The results differ dramatically from one estimator to another. Plus, varying input parameters and/or number of points may provide discrepancies.

See how zero padding effects your results. Manufacturing companies take note! Some estimators can detect signals 50 to 100 dB from main signal. See documented example! The unwritten rule of '30 dB is okay' (i.e. hidden) is no longer true.

Your school, college or university can too drastically cut costs and become more environmentally friendly by offering students electronic textbooks, manuals and syllabi in HTML, CHM, PDF, EXE, RTF or custom formats. These e-textbooks can be posted on the web, made available for download or handed out on floppies, CDs or DVDs.
SunRav BookOffice comes with two modules - Reader and Editor. The Reader module is what students use to view electronic textbook with, and the Editor module is used by faculty or specially trained employee to create electronic syllabi.
The benefits of SunRav BookOffice are much more that simple conversion of old paper versions to digital ones. First, educators now can use multimedia files to enhance learning experience. A short clip of video, a sound sample of bird song or a multimedia presentation of physics experiment can drastically increase students' understanding of the process and make it easier to remember the material. Plus, teachers and professors can record their lectures and make these digitized recordings available for next year students as a part of syllabus.
Creating electronic textbook is a very simple and straightforward process. One of the fastest ways is importing an existing MS Office document (MS Office required). When creating e-manual from scratch, users can take advantage of the Editor module that has all word processing, text editing, spell-checking and OLE object supporting features. Inserting hyperlinks, images, graphs, charts and multimedia objects does not require any programming or HTML skills.
In addition, it is possible to create e-textbooks in .exe format, eliminating the need for students to have the Reader module. And, because in some instances there are benefits to having a real paper copy, the program comes with a built-in printing option.
