Freeware Downloads for "Filter Coefficients Calculator"

The FIR Filter Designer app designs minimal-order finite impulse response (FIR) digital filters based on performance specifications you provide. The application attempts to find the lowest order (smallest) set of FIR filter coefficients that satisfies the given specifications. The generated filter has approximately unity (0 dB) gain in the passband.

The output of the design procedure is a list of double-precision filter coefficients (Text output option) or an implementation of the filter in C/C++, C#, Java or MATLAB/GNU Octave source code.

Function: 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) optimally fit a set of data points to polynomials of different degrees. See for detail in Matlab Documents (help sgolay). The sgolay function in Matlab can deal with only symmetrical and uniformly spaced data of even number. This function presented here is a general implement of the sgolay function in Matlab.

The Simulink model in this submission implements a 3-band parametric equalizer using a time-varying IIR filter, whose filter coefficients are generated by a S-function. This S-function implements the digital parametric equalizer design algorithm created by Sophocles J. Orfanidis. The user inputs the desired parameters to this S-function through a convenient GUI, with which the peak gain, center frequency and the bandwidth of a band can be specified. Dragging and moving the colored markers or the colored lines in the GUI changes the filter parameters.

For a full description of the models, refer to the September 2007 MATLAB Digest article. http://www.mathworks.com/company/newslette...sigmadelta.html We present a series of Simulink models to design a high-level behavioral model of a Sigma-Delta ADC. The high-level behavioral model has an Analog section and a Digital section that comprises a digital filter. We partition the digital filter into three cascade filters that use a total of 10 times less filter coefficients than the original filter. We then elaborate the first filter in the cascade in such a way that it requires no multiplications for implementation.

The gradient function in Matlab allows you to compute the slope of a curve along its entire length. But if your curve is a noisy one, then gradient will also be noisy. In this event one might desire to fit a moderately low order polynomial regression model in a sliding window, then differentiate that model. (Like a Savitzky-Golay filter.) All of this can be done efficiently in Matlab using filter. Note that this tool does not constrain the length of the support to be even or odd. Also, this tool uses pinv to generate the filter coefficients - a more stable and accurate methodology than does the sgolay tool on the file exchange.

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 Hz, to the function. Coefficients for FIR filter of length L (L always odd) are computed. This symmetric FIR filter of length L=2N+1 has delay N/SR seconds. Examples of use: Compute Gaussian filter frequency response when SR=1000,fco=50 Hz: freqz(gaussfiltcoef(1000,50),1,256,1000); Filter signal X sampled at 5kHz with Gaussian filter with fco=500: y=filter(gaussfiltcoef(5000,500),1,X); SR,fco are not sanity-checked.

van-der-Waals-Equation Calculator (vdw_calc) is a small command line tool to solve the van-der-waals-equation and calculate coefficients for different gases..

Returns equivalent IIR coefficients for an analog RC filter Usage: [B,A] = RC_FILTER(r, c, fs, type); R is the resistance value (in ohms) C is the capacitance value (in farrads) FS is the digital sample rate (in Hz) type is a character string defining filter type Choices are: 'high' or 'low' This function uses a pre-calculated equation for both of these circuits that only requires the resistance and capacitance value to get a true digital filter equivalent to a basic analog filter. The math behind these equations is based off the basic bilinear transform technique that can be found in many DSP textbooks.

ButterParam - Fast parameters for a digital Butterworth filter The calculation of filter parameters with BUTTER is expensive. Therefore ButterParam stores calculated parameters in a lookup-table to accelerate repeated calls with the same input. Example: x = rand(10000, 1); % test data [B, A] = butter(3, 0.6); y = filter(B, A, x); The relation of the processing times is: BUTTER=68% / FILTER=32%! With [B, A] = ButterParam(3, 0.6) we get: ButterParam=14% / FILTER = 86%, and the both calls together use 35% of the version with BUTTER.
