In this circumstance the fixed threshold detector would probably be best.
2.
The ASDTIC circuit used is based around an integrator and a threshold detector.
3.
This ensures that the recovered data from the threshold detector is adjusted to provide the correctly timed signal output.
4.
A threshold detector can be used to correct the amplitude levels although the exact time that the transition occurs may not be in the right place.
5.
The threshold detector generates a pulse 5 which starts as the waveform 4 crosses the threshold and is sustained until the waveform 4 falls below the threshold.
6.
While early versions of musical Tesla coils generally used zero crossing threshold detectors as a method of producing music through their spark output, Scott Coppersmith was the first person to design a complete MIDI-based Tesla coil system.
