[SI-LIST] Re: SI analysis on Low frequency signals

Certainly there is a possibility, but if your sensor is running at 500 Hz
you should be able to discard virtually all crosstalk and interference
with a low pass filter.  But, I have to ask: are you talking about 500 Hz
sine waves (for instance from an LVDT), or 500 bursts per second of
digital information.  Those are not at all alike, and require different
approaches
