Freeware Downloads for "Power Spectral Density Image"

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..

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.

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 .

Image Packer is a quick way to combine multiple images into a single one.

Why?
Mostly for efficiency and organization. APIs such as OpenGL and DirectX require power of 2 textures. A group of non-power of 2 textures could be merged into a single power of 2 image to improve texture memory usage. It's also handy when you have animations of a 2D sprite that you would like to keep in one file rather than have each animation frame as an individual file, which can hinder load times.

Features

- Loads BMP, JPG, PNG, and TGA files
- Exports a single image (with any of the above formats) plus a coordinate file in XML format.

Spek (IPA: /spdOOC*k/, d-de?bacon' in Dutch) helps to analyse your audio files by showing their spectrogram. Spek is free software available for Windows

Features:

Supports all popular lossy and lossless audio file formats thanks to the FFmpeg libraries.
Ultra-fast signal processing, uses multiple threads to further speed up the analysis.
High number of frequency bands for the best spectrogram quality.
Shows the codec name and the audio signal parameters.
Allows to save the spectrogram as an image file.

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.

The A·P·E Calculator helps to easily evaluate often needed (non)linear equations. This includes Sum Frequency Generation (SFG), Difference Frequency Generation (DFG), the wavelength relations in an optical parametric oscillator (OPO) as well as in coherent anti-Stokes Raman scattering (CARS) spectroscopy.

The conversion between wavelength, wavenumber, and frequency as well as different characterizations of pulses can be calculated.

Feedback as well as feature requests are appreciated.

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.

Accurate estimates of the autocorrelation function or the power spectrum can be obtained with a parametric model (AR, MA or ARMA). With automatic inference, not only the model parameters but also the model structure are determined from the given data. It is assumed that the ARMASA and the Automatic Spectral Analysis toolboxes are present..
