[Q]: Has anyone written a Lock-In VI or knows how to so?

Hi folks,

I was wondering if anyone has written a Lock-In VI or knows how to so. I am
planning to lock-in a signal at 100Hz max. I will have a programmed
reference signal (programmed in LabVIEW and output via one of my D/A
outputs), and a measured signal in response to that.

I am grateful for any hint. Thanks in advance, David.

Contrary to all appearances, it is not so simple, so I suggest you to contact
him.
(some problems are due to latencies of the OS, and to delays between the
measured signal and the programmed reference signal)
