The Elusive Glitch - Part 2 Hi All,
This month, I describe in my Technical Tidbit article (www.dsmith.org) a way to accurately pinpoint the source of a waveform glitch. It takes last month's article one step further than just determining if a glitch is likely coming from an external source instead of the circuit being measured. The technique uses an extra channel(s) of a scope to determine if the glitch is real or a result of external EMI and is reminiscent of the amateur radio transmitter hunts I participated in as a teenager (except in the time domain this time). Knowing this information can save a lot of engineering time in the lab and has become more important as circuits and measurement instruments have increased in speed. Equipment can now be affected by EMI sources that have not been a problem until the last few years. Doug -- ------------------------------------------------------- ___ _ Doug Smith \ / ) P.O.
