The Visible Spectrum Wavelengths

The Stellar Blackbody Radiation Curves model simulates the blackbody radiation curve of stars and how this leads to the observed color and luminosity of the star. If a star can be treated as a blackbody, the blackbody radiation curve of the star, the power density per area (or intensity) per...

Basic implementation of the Phase Spectrum Compensation (PSC) [1] method for single channel speech enhancement is included, along with a demo that illustrates its usage.References:[1] A.P. Stark, K.K. Wojcicki, J.G. Lyons and K.K. Paliwal, "Noise driven short time phase spectrum compensation...

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....

Simple example of the use of the FMINSEARCH function to fit the blackbody equation to the emission spectrum of an incandescent body for the purpose of estimating its color temperature and emissivity. fitblackbody.m is the fitting function. BlackbodyDataFit.m is a script that fits a small set of...

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...

The incoming signal is analysed via a FFT (Fast Fourier Transform), resulting in the familiar spectrum plot where the full audio spectrum is split into a number of narrow frequency bands. The outgoing audio is then regenerated by an Inverse FFT. The interesting bit is that the plug-in lets you...
