add phase to the sinusoidal signal

[gfds]

Hey everyone,

I have issue. I don't knew how can i add phase to the sinusoidal signal? I have two sinusloids whith are of variable frequency (variab. freque. - i suppose that is not a problem for solve my problem). Tension and curant (my two sinusoids) i need delay each other. 

 If anyone can give me help, please.

hi,

  If you are generating a sine uisng express vi,phase input is there.wire any value to it and get the delay...

Thanks and regards,

Thanks SrikrishnaNF for your reply,

These sinusoids I've taken from sensors and i need edit them.

Hi ,

  If that is the case...please check the delay values express vi...

Thanks and regards,

Hey SrikrishnaNF, if you mean whot i insert previous it doesn't work. After diagram run is appered an error that two signal are not the same. And i think that it is not a delay of signal phas.

(?)

 

I calcul the paramet reel and imaginary from two singnal. For my experience i need delay with phase one signal unto the second.

Hi gfds,

Maybe you can use cross-correlation between your signals.

Thank you Micael_ for help

How can I use cross-correlation block for solve my issue?

I've attached my resultat of using this block. Frequency is in range 25kHz - 35kHz with showing resonance.

I thougth you wanted to calculate the delay between the sinuses...

If you want to add a delay, you can just acquire a little more samples and then remove a part of the signal at the beginning of an array/the end of the other.

Is there a problem with your current acquisition? It seems not to be a sinus.

Maybe it would be more convenient if you post your question in the french forum.
