Spectrum Gym

The inputs are the imf's amplitud and the imfs instantaneous frequency. The outputs are the Marginal Hilbert Spectrum (mhs) amplitude vector and a frequency vector corresponding to the amplitude vector. In order to obtain a more interpretable graph the instantaneous frequency vector can be... Platforms: Matlab

Tuner for instruments like guitar with a spectrum analyser and ton generator. It is possible to adjust the guitar or an other instrument. The program ist written in Java. The enduser need a mikrofon for tuning the guitar. Platforms: Windows, Mac, Linux

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... Platforms: Matlab

A Simulink model that generates and displays a simple cosine wave. The model computes the cosine function using the continuous phase method, which is based on Euler's formula for the complex exponential. The cosine generator is provided as a subsystem, which the user can copy-and-paste into other... Platforms: Matlab

Set of functions providing the attenuation and energy absorption coefficients of x-ray and gamma-ray photons in various materials, based on NIST report 5632, by J. Hubbell and S.M. Seltzer.X = PhotonAttenuation(Material, Energy, Options, Thickness)Function providing the attenuation and energy... Platforms: Matlab

A single program which plot Spectrum of AM modulation.For more information, visit: http://www.matpic.com Platforms: Matlab

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... Platforms: Matlab

These programmes are not heavily commented but infact are very simple and intutive to understand the Frequency hopping and related tasks.I have made two files for frequency hopping, one of them is not showing 6 proper impulsive peaks but other programme is infact showing them, In DSSS i have...

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... Platforms: Matlab

Features:1. the program calculates the matter power spectrum, temperature spectrum, polarisation- and cross-correlation spectrum of a curved or flat Friedman-Robertson-Walker universe.2. it calculates the age of the universe, sigma8 and the age of the first start formation.3. massless neutrino's,... Platforms: Matlab

Find the pitch of a power spectrum (signal) as per the afferent/efferent neural crossover. This occurs between the Lateral olivocochlear efferents and the inner hair cell afferents. Platforms: Windows, Mac, Linux

ZXTapeTool is a tool to manipulate tape archives for ZX Spectrum emulators Platforms: Windows, Mac, Linux

The file included is a library containing the Masked Subsystem. This block displays if there are any blocks in your model whose opening can be controlled (ie Spectrum Scope). If there are, the block allows the user to double-click to toggle this option on or off. Platforms: Matlab

Computer application with implemented Okumura-Hata propagation prediction model and free space propagation loss model.

GaussSum parses the output of ADF, GAMESS, GAMESS-UK, and Gaussian to extract useful information: progress of geometry optimisation, UV/IR/Raman spectra, MO contributions and more. Features . Convolute UV-Vis spectrum . IR and Raman visualization Platforms: *nix

3SA (Spread Spectrum Simulation Application) is an interactive application that allows the user to select an input audio signal (a pre-recorded .wav file or a microphone) and "watch" as it is processed, transmitted, and received in a direct sequence spread spectrum simulation. It is intended to... Platforms: Matlab

Java Data Processing Project aims to manipulate text file containing scientific data such as time/intensity scan or spectrum. Jdpp provide large flexibility to read all possible time duration and date format. It is originally design to treat MS data. Platforms: Windows, Mac, Linux

open82 is a freely-licenced replacement firmware for the Sinclair ZX Spectrum. Just like the original, it is based on the firmware for the Sinclair ZX81. It is released under the GNU General Public License. Platforms: Mac

Cover Slip is an iTunes visualizer for Mac OS X 10.6 (note: Snow Leopard only!) that displays a swinging album cover, song information, and a small timeline and audio spectrum bar display. The bars can dance with the music; alternatively, you can choose to view a spectrum circlet instead of the... Platforms: Mac

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... Platforms: Matlab
