Creating Piece-wise curves for analogue signal output

[haza16]

Hi guys,

Im a LabView newbie, only just started working with it last week, but have completed many online tutorials so far.

I have a project that i am working on currently that requires the representation of a certain waveform, with many of the parameters able to be changed dynamically on the fly. What im having trouble with is creating a piece-wise linear representation of this waveform.

I think that I need to have it piecewise as the following variables are ones that i need to change:

On the voltage axis:

Peak voltage output (analogue)

Trough voltage output (or offset, also analogue)

On the time access:

Voltage Rise & Fall times

Pulse width

Pulse frequency

If anyone has done something similar, or if someone can point me on the right track it would be much appreciated!

Thanks in advance

Adam

Hello Adam

Are you looking to do this on the fly or are you wanting to generate a finite signal in the software with changes in the voltage and time axis.

I amsume you want to generate a signal from your Multifunction DAC board. So you would like to generate some finite waveform signal so that you can change the the configurations of the waveform before generating a new finite signal.

You would have to take a look at the "Gen Mult Volt Updates-Int Clk.vi" example from the example finder in LabVIEW.

There are some signal generation functions in the analyze palette in the all functions palette.
