Hello everyone,

I have searched the related question in the forum, and I found this topic:

How to use sigmastudio software to realize an external potentiometer to control phase, the phase of the range is 0 ° to 180 °? 

 

Bob gave the answer, but I still have some questions about the "Hilbert Transform" (I can not fine the answer from the wiki, because the page is gone.)

 

About the Hilbert Transform,

The upside output is 0 degree or 90 degree?

 

from the Bob's answer, this implement 350 degree adjustable, if I only want to adjust 0 to 180 degree from the ADC, how should I do? change the sine and cosine LUT table? and how to make a step, like 0, 10, 20, ....., 180 degree

 

Please help me for the question,

Thanks!

 

Alvis.
