Valve Noise

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 submission was created by Valery Tchkalov and Steve Miller to help engineers understand parameterization of hydraulic valves. The included white paper, simulation models, and MATLAB scripts cover the structure of a valve model, examples of how to use optimization algorithms to tune your...

This simple simulation shows the implementation of FbLMS algorithm for a single channel feedback 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.FbLMS...
