wavelet analysis in excel
Post: #1

Hi I'm Pavel, the head of the meteorological center, I would like to receive detailed information about wavelet analysis in Excel. I really need this for the analysis of the temporary yards of the meteorological station for 90 years. Help me please.

The toolbox includes the discrete wavelet transform, the inverse wavelet transform, the wavelet-based de-noise, and an associated plotting utility. Transformations and decontamination algorithms were implemented in a DLL using C ++, while user interfaces were developed using Visual Basic for Applications (VBA) forms. A simple technique was used to automate the transfer of data, associated properties and user selections from the spreadsheet to the DLL and calculated values ​​from the DLL back to the spreadsheet.

The waves were developed independently in the fields of mathematics, quantum physics and electrical engineering, but the interactions between these fields over the last few years have led to an increase in the number of wavelet applications and in the amount of research related to wavelets, Applied and theoretical. Just to mention a sample, wavelets have been applied in the areas of compression and rapid transmission of medical imaging, video compression, image recovery and digital libraries, digital communication, power electronics, antennas and electromagnetism [8], and even dynamics Of fluids. Basically, any field involving data processing and analysis can benefit from wavelets due to their properties, which include the simultaneous localization of signal components in time and frequency domains, which is not possible with Fourier analysis. Consequently, wavelets are increasingly entering classrooms and laboratories in the form of both theoretical and applied subjects. Our goal in this article is to take advantage of the simplicity and familiarity of spreadsheets for instructors, students and other computer users and to encourage the exploration of wavelet analysis and its applications in educational topics and research activities.
