Simulate a Current waveform

[LeoLiu]

i only know how to simulate a sine wave, so how to simulate a current wave, anybody can show me?

Hi LeoLiu,

can you explain what a "current waveform" exactly is?

[LeoLiu]

now im simulate a sine wave, i wanna see the waveform respect for current, how to do that?

[GerdW]

Hi LeoLiu,

"sine" is describing the signal's value over time, but "current" is describing a physical unit!

So please explain in more detail what you want!

[LeoLiu]

Well, my work is using CompactDAQ to monitor current and voltage from power network, and show the waveforms, make a analysis.

But before that, i wanna  simulate it by labview

Hi LeoLiu,

         Would you be confused if I said that you could view your current as a sine wave?

         On a serious note, could you please send in your code? Just so we can have a better understanding of where you are at so far.

i just dont know how to start

yes, you are right, the current sine wave is exactly i wanna see

just show me how to display this

i have attached my vi

[GerdW]

Hi LeoLiu,

you already display waveforms! So what else should we show you?

(I wonder why you didn't use another ExpressVIs to calc the averages )

[JohnMc19]

Hi LeoLiu,

Your vi seems to show show the required waveforms. You are currently viewing the frequency domain of a simulated signal. To see the current of this signal it will be down to you using formulae to extract it from a power waveform.

which is the best vi to calc the averages?please tell me ~~
