how to create a periodic staircase (both up and down)

[kathy1027]

Hi,

I just study Labview for 2 months. I would like to create a periodic staircase, which I could control the time and amplitude of each step. What should I do?

I try to use simulate signal generation, but it only up or down. I prefer a  convex shape waveform (similar to the picture shown below).

Sincerely,

Hi kathy,

I would like to create a periodic staircase,

Your image shows some up/down steps in the signal: all you need is to create a waveform consisting of several rectangular parts…

which I could control the time and amplitude of each step.

Each step is defined by its amplitude and length: you can easily create a SquareWaveform for each step!

When your parameters are provided in an array you could use an autoindexing FOR loop…

Hi Gerd,

Thank you for your reply.

I have tried your advice on Labview, but I don't know how to combine those square waveform together in one x-axis. Could you make a sample vi to explain it? 

Sincerely,

Hi kathy,

I already mentioned the function SquareWaveform - I also explicitely mention AppendWaveforms…

(Did you even tried to search for that function on your own in the waveform functions palette?)
