Build a trapezoid in DasyLab6 S

[PHeine]

Hello everybody,

I have the following issue. I want to build a trapezoid signal with ranges -2 to 2 Volt, 5Hz and slopes of 4 ms.

I even can't find where to build a trapezoid 😞 Help, please.....

Thanks in regard,

PHeine

Does DASYLab S have the Sequence Generator?

If not,  you have to create a Generator with a Triangle Waveform, and then use a Scaling Module with Limits to cut off the top. 

I don't have DASYLab 6 anymore, so I can't make you an example that you can run.

I just tried the following...

Generator with Triangle Wave,  5 Hz, Amplitude of 50, connected to a Scaling module, with the scaling set to1x + 0, and the lower limit of -2, upper limit of 2.

Hi there. I think what you are trying to say is I only get a sloped rising edge.

I also want a sloped falling edge.

I have made a drawing and uploaded it into a fotobucket:

I hope this works. I've never done this.

Thanks anyway for helping me.

Did you use a Triangle wave? If you cut off the top, you will have both a sloped rising edge and falling edge.

Here are some screen shots from my example.

Note... you could have attached the JPG to the post... the attach dialog is at the bottom, below Submit Post.

Wow, thanks for the solution guys! It works!

I'll ask somthing later on about a fourier analyse

about this signal.

Again, thanks a lot.
