There are some videos about "Synchronous Detection" in the library, just search for the words and look at parts 1 to 4. Probably that technique can help you with your project. When you send a mail to Chris Keeser or Dave van Ess you can ask for the complete project files.
Bob-san, Thanks for nice follows.
I didn't see all of cypress video,
The words, "Synchronous Detection" is first time to heard.
I will be watch it as soon.
Anyway, I'm not so serious to about this module.
Because, this too much consume UDBs.
There is no practical to real use.
It's just to know what's PSoC can do.
