Re: [UM-LINUX] waveform generator in linux

[John Demme]

I would be pretty trivial to build use an op amp to get up to the 12V.  Plus, with a sound card, you get two channels (more if you have 5.1 on your computer)... Writing the software to output waveform data to the sound card would be interesting... Better yet, you could probably just use a program to generate an x Hz waveform in wav format and dump that to the device.

If you don't plan to go over 22.05kHz, you can probably just build a
powered amplifier connected to the output of your sound card; this is
probably the cheapest way. Also, I don't think the PCI bus supplies +12V,
so I don't know how someone would build a card with that output rage...
