- Vibration Response Spectrum
- License: Freeware

This program calculates the Vibration Response Spectrum (VRS) for a base input Power Spectral Density (PSD). The base input PSD must be in terms of acceleration. The VRS uses point-by-point multiplication of the transmissibility function times the base input PSD. It is thus more accurate than Miles equation..

- Baseband numeric transmission
- License: Freeware

This script is intended to illustrate the concepts of eyediagramm, constellation, ISI and to understand the effects of additive noise power, channel frequency band restriction, number of possible states within a symbol period, affecting the quality of the transmission. Three methods are employed for low-pass filtering: - classical low pass filter (actually two order Butterworth) creating ISI. - raised cosine filter in order to illustrate the possibility of suppress ISI . - Pseudo filtering by increasing risetime and falltime of ideal rawcode .

- Fully Automatic Signal Spectrum Analyser
- License: Freeware

This program operates as a signal spectrum analyzer and a distortion meter at the same time. It can accept any numerical data representing few cycles of a signal. The data do not need to be equally separated. At least ten data points per cycle are needed. Higher number of data points will of course produce better results. The main advantage of the program is its ability to automatically detect the fundamental frequency. Any part of the spectrum within the frequency band f1-f2 can be calculated and plotted.

Fourier Transform is one of the basic tools to analysis a large scale of problems related to time-series analysis.
There are very few free open source software which can be use in any platform for Fourier Transform and Power Spectral analysis with simple input and output. This tool can only be used by click of mouse i.e. user need not to learn Matlab or R only for Fourier Transform. Here in this tool Fast Fourier Transform (FFT) is implemented with various window function for Power spectrum analysis.

- EZFFT : An easy to use Power Spectrum (FFT)
- License: Freeware

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. In this latter case, T must be equally spaced (as obtained by LINSPACE for instance), and it must have the same length as U. If T is not specified, then a 'sampling time' of unity (1 second for instance) is taken.

Computers, the restless machines with unprecedented precision are helpers to human beings at many tasks, these days. Almost any challenge involving heavy-calculation from predicting population growth to modeling complex space objects requires computing power of today. Math software is still the 'king of software products' as it allows for calculations required in any aspect of modern life. However, often math software is bulky, overloaded with useless 'features' and requires reading 300-pages manual before attempting to use it.

- Continuous Morlet Wavelet Transform
- License: Freeware

This article consists of a brief discussion of the energy density over time or frequency that is obtained with the wavelet transform. Also an efficient algorithm is suggested to calculate the continuous transform with the Morlet wavelet. The energy values of the Wavelet transform are compared with the power spectrum of the Fourier transform. Useful definitions for power spectra are given. The focus of the work is on simple measures to evaluate the transform with the Morlet wavelet in an efficient way.
