The Digital Filter Design Utility is software that allows you to interactively specify and design floating point digital filters. This utility was created with LabVIEW and the Digital Filter Design Toolkit and compiled into a stand-alone application for your use. The full Digital Filter Design Toolkit contains a complete set of filter design tools for designing a wide range of floating point and fixed point digital filters within an open environment, using an easy-to-learn interactive graphical programming language.

Digital filter design

Introduction to digital filter design in labview

The Interactive Digital Filter Design Utility is a compiled LabVIEW applicaiton that allows you to interactively specify and design floating pointdigital IIR filters and FIR filters online. This utility was created with LabVIEW 8 and the LabVIEW Digital Filter Design Toolkit to provide an interacive tool for digital filter design. Only a portion of the functionality available in the LabVIEW Digital Filter Design Toolkit is used in this utility. The full toolkit contains a complete set of filter design tools for designing a wide range of floating point and fixed point digital filters. Once the LabVIEW plug-in has been installed, the Interactive Digital Filter Design utility will run within the box below.

Download the full source code for the LabVIEW Interactive Digital Filter Design Utility here . This allows you to run the same Interactive Digital Filter Design Utility from your Windows PC without being connected to the web.


The Digital Filter Design Utility can be run on Windows OS within this web page or downloaded for offline use. You will need to download and install the free LabVIEWRuntime Engine and enable the browser plug-in for local execution. Visit the following link for instructions on installing the LabVIEW Runtime Engine and configuring the browser plug-in to enable the Interactive Digital Filter Design Utility and other online web based LabVIEW applications.

How to use the digital filter design utility

The Digital Filter Design Utility provides two filter design tools for either classical design or design bypole-zero placement.

Classical design mode allows you to specify a FIR or IIR filter design by setting design parameters such asfilter type, sampling frequency, passband/stopband edge frequencies, passband and stopband ripple levels, and stopbandattenuation. You can select from design methods that include Butterworth, Chebyshev, Inverse Chebyshev, Elliptic, Kaiser Window,Dolph-Chebyshev, and Equi-Ripple. LabVIEW will then use the design parameters to suggest a filter meeting as many of thosespecifications as possible. You are then free to optimize the design to meet your needs.

The pole-zero placement interface allows you specify the location of multiple poles and zero either byentering the coordinate locations directly or graphically by clicking on the z-plane. The resulting filter is then displayedusing the Bode Plot.

The resulting filter coefficients can then be saved to a text file to facilitate deploying your design on realhardware or for further analysis.

sure. what is your question?
okay, so you have 6 raised to the power of 2. what is that part of your answer
I don't understand what the A with approx sign and the boxed x mean
it think it's written 20/(X-6)^2 so it's 20 divided by X-6 squared
I'm not sure why it wrote it the other way
I got X =-6
ok. so take the square root of both sides, now you have plus or minus the square root of 20= x-6
oops. ignore that.
so you not have an equal sign anywhere in the original equation?
is it a question of log

or infinite solutions?
The answer is neither. The function, 2 = 0 cannot exist. Hence, the function is undefined.

Yes, Nanotechnology has a very fast field of applications and their is always something new to do with it...

good afternoon madam
what is system testing
what is the application of nanotechnology?
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
anybody can imagine what will be happen after 100 years from now in nano tech world
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
silver nanoparticles could handle the job?
not now but maybe in future only AgNP maybe any other nanomaterials
I'm interested in Nanotube
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
can nanotechnology change the direction of the face of the world

At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.

the Beer law works very well for dilute solutions but fails for very high concentrations. why?
