Fractal Noise

Used on cellular phones to filter outbackground noise. Measure the signal to noise ratio of an audio input in realtime. Pass speech but give silence where the input is noise (hiss, snap crackle and pop).Includes a tutorial on how to use statistics (correlation coefficient) to calculate the signal...

This simple simulation shows the implementation of FxLMS algorithm for a single channel feed-forward active noise control system. Here, the controller generates an "anti-noise" signal to result a destructive interference at the sensor position. The objective is to minimize the noise residue.The...

Suppose that you have a signal Y (Y can be a time series, a parametric surface or a volumetric data series) corrupted by a Gaussian noise with unknown variance. It is often of interest to know more about this variance. EVAR(Y) thus returns an estimated variance of the additive noise.EVAR provides...

This script implements Mandelbrot's method for generating realistic stock price graphs based on a simple fractal rule. It keeps subdividing the graph by three and adding a "generator" to create fractal behavior.Reference:Benoit B. Mandelbrot, A Multifractal Walk down Wall Street, Scientific...

This is a program that draws the famous Sierpinski Triangle and Koch Snowflake. It's just like hundreds of other programs written just like it! This is a classic example of recursive programming. As an applet, it draws the triangle. As an application, it draws the snowflake. I would be interested...
