Political Spectrum Survey

Multi-Platform Survey Architect is a Java-based application for survey creation. Initial versions are geared toward the creation of web-based surveys in PHP / MySQL. The program is designed to be extensible (hopefully) to the extent that any language can be used for output.

This is an FSK modulation spread with a PN sequence generator.It is a simulation file that illustrates the effects of spread spectrum communications.I am interested on collaboration.

SSA generates a trayectory matrix from the original series by sliding a window of length L. The trayectory matrix is aproximated using Singular Value Decomposition. The last step reconstructs the series from the aproximated trayectory matrix. The SSA applications include smoothing, filtering, and...

EZFFT(T,U) plots the power spectrum of the signal U(T) , where T is a 'time' and U is a real signal (T can be considered as a space coordinate as well). If T is a scalar, then it is interpreted as the 'sampling time' of the signal U. If T is a vector, then it is interpreted as the 'time' itself....

Digital signal generator (sumulator) with power spectrum display and sliders for "real time" control, useful for teaching and demonstrating the power spectra of different types of signals and the effect of signal duration and sampling rate. Version 1.1 adds sound output. The signal slider selects...

This is a little script that adds several Gaussian or Lorentzian functions with the appropriate full width at half max and height to generate and plot a spectrum. The input is an array containing frequency vs oscillator strength, desired fwhm of the peaks and method for generating the spectrum....

The radially averaged power spectrum (RAPS) is the direction-independent mean spectrum, i.e. the average of all possible directional power spectra. The radially averaged power spectrum provides a convenient means to view and compare information contained in 2-D spectra in 1-D. This function...

Spectrum scope makes it easy to compute and display the fft of a live signal. You feed it your time series data, and it does the rest. It works very nicely with the Timer objects introduced in R13, and with Analoginput objects (from the Data Acquisition Toolbox).Here's a simple example, assuming...
