Low Pass Filter

[extale]

Hello!

I have a question. Can you give me a hint on where to download libraries/tools for a lowpass filter. I use VS Express Edition 2005, (VB.Net). Thank you!

Rgs, Andrew

PS: I am also interested in signal processing such as FFT or Analysis in Time Domain (Average, RiseTime, etc) that can be done in VB.Net. Thx!

Here's one, but it's not free, and not that cheap either.......

Thanx!
Do you also know how to do convolution of two Signal-Arrays with VB?

Off the top of my head, no. That would be a real project in vb.net. That doesn't mean to say it can't be done. Here's an article on FFT from the code project. I'm afraid to say that it is in c++. But i would think that most of these articles are, due them mostly using unmanaged resources for bit reversal and such. Here's the link, even if you can't read the code the article may be of use.
