zsim is a framework for simulating, analyzing, controlling systems defined by Matlab classes. It functions somewhat like simulink in that the user chains together different modules to create a complex simulation structure, however there is no graphical user interface. All of the modules in zsim are objects created from Matlab classes derived from the classes contained in this package.
I created this framework because I was running...
Query and filter builder.
The component allows end-users to define queries and filters for single datasets and groups of datasets linked as master-detail or differently. It automatically substitutes the dataset for the generated query and...
Easy Filter Applet is a generic filter that allows people like students, scientists, engineers, ... in "image processing" to show their work in a web interface. It's not a static GUI !! -
Users can interact with filter's...
This script adds to any html table a "filter by column" feature that enables users to filter and limit the data displayed within a long table. It even works on tables with uneven rows.
The script automatically adds a filter...
This script removes the dollar sign ($) and commas (,) from a a text box. It is useful if you require input of only numbers. You may also modify the script to filter out whatever characters you want.
When the user...
This function returns coefficients of Gaussian lowpass filter.
Advantages of Gaussian filter: no ringing or overshoot in time domain.
Diasadvantage: slow rolloff in frequency domain.
Pass SR=sampling rate, fco=cutoff freq, both in...
Savitzky-Golay Smoothing and Differentiation Filter
The Savitzky-Golay smoothing/differentiation filter (i.e., the polynomial smoothing/differentiation filter,
or the least-squares smoothing/differentiation filters)...
Recently needed to see the effects of a CIC decimating filter but realized that with my new license of Matlab, I did not have access to the Filter Design Toolbox. This is a quick attempt at a simulation to re-create the effects of CIC-decimation...

Derives the transfer function for digital implementation of a first order RC low pass filter and plots the step and frequency response.
For details, refer to the post:
The model describes the Active power Filter for High Voltage DC power Supply. The Active Filter can be used in any other applications also.
It is a new block simulink signal library called the Phase Filter.The transfert function is F(p)=(1+T1p)/(1+T2p).Students can change parameters T1 and T2 time constants of filter.The phase filter in automatic control is for Corrector block and...
MISO_FIRWIENER(N, X, Y) computes the optimal FIR Wiener filter of order N, given any number of (stationary) random input signals as the columns of matrix X, and one output signal in column vector Y.
Requires BLOCK_LEVISON.M, also on the...
In wireless topology we using filters as main part of system, we proposed a flexible filter for multi-purposes working at ISM band frequency. Obviously the filter idea works by splitting the Band Pass Filter into two types H.P.F & L.P.F...
