	Crystal Oscillator Reference
		A crystal oscillator (sometimes abbreviated to XTAL on schematic diagrams) is an electronic circuit that uses the mechanical resonance of a physical crystal of piezoelectric material along with an amplifier and feedback to create an electrical signal with a very precise frequency.
		The output frequency of a quartz oscillator is either the fundamental resonance or a multiple of the resonance, called an overtone frequency.
		If this is not possible, the number of distinct crystal oscillators, PLLs, and their associated clock domains should be rigorously minimized, through techniques such as using a subdivision of an existing clock instead of a new crystal source.

	The Theory of the Edgetone Oscillator (Site not responding. Last check: )
		With the assumption that the edgetone oscillator is a transit time feedback oscillator, analogous to electronic oscillators, explaining edgetones theoretically is reduced to two independent problems, predicting the fT product sequence, or values of k, as a function of stage number, and predicting the transit time T of a jet particle from aperture to edge.
		In the klystron oscillator the electrons in interacting with the oscillating electric field either lose energy to the electric field, in which case oscillations continue, or gain energy from the field in which case oscillations die away.
		To summarize, the phase velocity of the jet wave in the edgetone oscillator and in musical instruments such as the flute and organ flue pipe is not a small fraction of the jet particle velocity, as stated to be the fact in most texts and papers dealing with this oscillator and these musical instruments.
