i need to be able to generate simple analog waveforms (square pulses) at a given frequency (1-1000Hz) and voltage (0-12V) for a given period of time (0s-60s).
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...
