Changing phase angle of signal dynamically over time
Greetings All
I'm trying to have my vi change my phase angle from 0 to 360 over time
I can get it to work by manually changing/adjusting the phase slider
but how can I have it increase or decrease over time automatically/dynamically.
Example:
Have 1st signal phase change from 0 to 360 over a second and repeat until time target to stop variable is reached.
Have 2nd signal phase change from 0 to 360 ten times a second and repeat until time target to stop variable is reached.
The reason I'm using mathscript is due to the fact I will be creating multiple signals
with multiple sin and cos that include about 50 terms and using the sin and cos vi's
would get vary messy very quick. And I don't think having several timers would work in one loop. I'm Basically testing out different ways standing waves are created using multiple signals.
Some ideas I had but not sure how to implement/or if they would work:
1) I was going to tie the x value back into the phase/degrees1 variable and multiply then do a modulo 360 so whatever time it is it would only go from phase 0 to 360.
(the problem is it looks like it skips values and not sure how to implement on multiple signals in same loop running at different speeds)
thanks
