Can some one please help me..
I am looking to create and Ideal waveform. I have a Signal coming into a waveform chart from an accelerometer attached to the seat of a rowing machine. I want to copy the waveform made with the accelerometer and then use this waveform as a guide for everyone else to follow when they are on the rowing machine.
Is this possible to do??
HELP????

Well in principle it is possible only with ideal signals. A real waveform is never equal to another. Then you´ll have to think in signal analysis such as power spectrum or the RMS of the signal for your purpose.

Creating the waveform can be both easy and frustrating. It is "easy" because all you need to do is record someone doing the ideal thing on the rowing machine, then play that back. It is frustrating because you need to get someone to do the ideal thing on the rowing machine. I would definitely start with an actual recording. At that point, you can smooth it, average it with other waveforms, or otherwise modify it to get your ideal. Make sure you have a very good handle on what "ideal" is before you start.

Is it possible to record the signal and the play the signal continously on the waveform chart?
or can I create it using the dimensions

I have a professional rower that will rower I only need to capture one perfect stroke and then play it continously on the waveform chart.
How can u record signals on labview?

If you have an accelerometer you need to use it's pre-amp which should give you a representative voltage. You read that voltage output with a Data Acquisition (DAQ) card or module and LabVIEW's DAQmx VIs. This will give you a waveform datatype that includes timing information and an array of data that represents your real world signal.
DAQmx makes it very easy once you understand how to use it properly. There are many examples...

Here is a little game
follow the line 🙂
replace the Best indicator with your ideal and the Move control with your sensor input
