output from H(s) to AO

[Asan]

Hello,

I am required to place poles and zeros to signal taken from accelerometer and pass it through a low pass filter before sending it to AO. The poles and zeros are placed by H(s). I am not sure how to send the output from H(s) to AO. I am attaching a simple vi. With broken wires. Could you kindly look at the file and suggest the solution.

For your information I have also tried to use 'AO update channel' instead of 'AO generate waveform', this time I could wire them up but the system 'hang' after first AO update.

Thank you very much

Regards

Asan;

The first thing you need to figure out is if you are going to use a point-by-point or a buffered approach. In case you use the first one afore mentioned, you can use AO Update Channel.vi. The input of that VI needs to be the voltage value that will be output on the channel.

In case you use the buffered approach, you can refer to one of the Labview shipping examples that shows how that is accomplished. The best one for you to start with is the one at Search Examples->I/O Interfaces->Data Acquisition->Analog Output->Multiple Point (buffered) Analog Output.

Hope this helps.
