How to create different types of signals ?

[Mohammed_Kandeel]

Hello every one,

I try to create different types of signals like PWM with specific Ton and Toff,

sine wave, sawtooth and triangle wave, so if any one can help me or give me a blog to read.

Thanks in advance.

Hi Mohammed,

have you had a look into the signal generation function palette?

Hello GerdW,

Yes i look at it at first of all and the following video "https://www.youtube.com/watch?v=56OgsDL4INc&t=491s" is wonderful, but i don't need to make it with function generator

i want to build it with loop iteration and some logic function.

Your question is way too generic to provide an answer. Do you just want to simulate a few waveforms and display the new result when the parameters have changed or generate them continuously? Is this just a simulation or do you want to create an analog output? Whats your hardware? What's the rate and frequency? What's the purpose?

hello altenbach,

I think it's not our first communication, i will answer your question i hope you then help me.

Do you just want to simulate a few waveforms and display the new result when the parameters have changed or generate them continuously?

I want both, like i want to generate square wave and manipulating the ton and to off of the wave.

Is this just a simulation or do you want to create an analog output?
it just for simulation.

What's the purpose?

it's about earning skills make things with different ways, like if i don't have function generator what will be the solution then ?.

Yes, we communicated. So, what are you having problems with? Writing the program or figuring out the math to make the signal shape. Both are quite easy, so I would recommend to just try a few simple things and combine them into a bigger program later. (E.g. try a simple square wave in a while loop,) Also do some tutorials and look at the examples that come with labview. (Help...find examples).

If you get stuck, ask specific questions and show us what you tried.
