I need to create random signal generator in Electronic Workbench, so can you help me?

It needs to have at least three period and every half period needs to be different from one before and after by V and t



Thanks!

The image you tried to post is on your C drive. We won't be able to see it until you get it online. You can upload the file here as an attachment - use the paper clip icon when posting.

Do you mean a random signal generator or an ARBITRARY signal generator. These are actually two very different things. What you seem to be describing is an arbitrary generator. But a little more description would be useful.

I think you are right. Its an arbitrary generator.
It needs to have three or four period which could creating a loop.
Every half period needs to be different by amplitude and time duration.
And must be build in Electronic Workbench.
Any information are welcome.

Use a microcontroller with an analog output or in combination with a DAC (if it doesn't have an analog output) and generate your signals.

Hello ,

@ mik3
And must be build in Electronic Workbench.
This is not in hardware, but software.

@Ivika

Can you make a table of values and loop this in Electronic Workbench ?
I do not know the software.

I am sorry for the misunderstanding, I thought he meant his electronics lab!!

I must build a generator in program Electronic Workbench which generate signal like this in example. Every half period needs to be different by amplitude and time duration/frequency.
How to built that generator in electronic workbench and what
components to use?
Thanks!

Example :
first half period: voltage: 0.5V, frequency: 8Hz
second half period: 1V, 7Hz
third half period: 2V, 6Hz
four half period: 3V, 5Hz
five h.p.: 4V, 4Hz
6 h.p.: 5V, 3Hz
7 h.p.: 6V, 2Hz
8 h.p.: 7V, 1Hz
9 h.p.: 0.5V, 8Hz...

Hello,

You know the frequency, so you can calculate the time a halfcycle takes.
What should be the shape during this halfcycle ?

Do you need some other information to help me? Is there anything else you can tell me so that I can use for my project?

I have made some progress with my project, so I would like you to see what is it about and let me know if maybe you have some other solution? Take a look at the attachment.

Those of us without EWB cannot read your files. We therefore cannot see your schematics. Can you save them in a pdf format? Or some other more common format?
