Search Results for "frequency analysis"

Ever had a bunch of ASCII data that you would like to have a quick look at in frequency domain, but don't want to fire up some bulky analysis software package just for that? Well, I have... So I wrote this tiny tool. It is based on fftw (www.fftw.org) and boost's program options (boost.org). cli-fft is really simple: All it does is to receive ASCII data from a file or standard in, FFT it and write out the result into a file or to standard out.

SonicData is a data collection and analysis program used in connection with a sound card voltage-to-frequency interface. Its intended use is for laboratory instrumentation.

WikiVis is a tool to analyze Wikipedia based on several aspects. The main objective is to visualize the conclusions of this examination, which focusses on the editing frequency and relevance of articles and categories as well as the activity of users.

For a given signal, pstool calculates a one-sided power spectrum, i.e. the portion of a signal's power falling within given frequency bins. This is done by employing a one-dimensional real-to-complex FFT routine on an MPI cluster.

A software to perform a full analysis of heart rate variability (time domain, frequency domain and nonlinear dynamic) for research purpouse and, I hope, for improve diagnostic power of Holter ECG recording.
