A time-varying digital filter can easily be implemented in LabVIEW, and this module demonstrates the complete process necessary to develop a digital filter that operates in real-time and responds to parameter changes from the front panel controls. An audio demonstration of the finished result includes discussion of practical issues such as eliminating click noise in the output signal.
This module refers to LabVIEW, a software development environment that features a graphical programming language. Please see the LabVIEW QuickStart Guide module for tutorials and documentation that will help you:
•Apply LabVIEW to Audio Signal Processing
•Get started with LabVIEW
•Obtain a fully-functional evaluation edition of LabVIEW

A time-varying digital filter can easily be implemented in LabVIEW. The screencast video of walks through the complete process to develop a digital filter that operates in real-time and responds to parameter changes from thefront panel controls. The video includes an audio demonstration of the finished result and discusses practical issues such as eliminating clicks in the output signal.

Download the source code for the finished VI: filter_rt.vi . Refer to TripleDisplay to install the front-panel indicator used to view the signal spectrum.

what is the application of nanotechnology?
Stotaw
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
Prasenjit
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
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
Prasenjit
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
Damian
silver nanoparticles could handle the job?
Damian
not now but maybe in future only AgNP maybe any other nanomaterials
Azam
can nanotechnology change the direction of the face of the world
Prasenjit Reply
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?
