Abstract
A glitch trigger circuit for measuring glitches that appear on power line signals includes two comparators and two independently controllable voltage trigger levels to allow proper trigger on glitches of unknown polarity. A high pass filter rejects the power line signal while passing the glitch signals to provide triggering on glitches with voltage amplitudes less than the voltage amplitude of the power line signal.
