Spectrum Radiology

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...

The script uses only one transmission symbol per frequency hop.

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...

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....

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...
