It should produce a pretty good signal - it will be spurious products that will give distortion. So may be there is too much feedback in the circuit. That said, so crystal oscillator units are designed to give a digital square waveform out. They take the basic sine wave and square it up so that it can act as a clock oscillator for a logic / digital circuit.
Well it's not digital to analogue in the conventional meaning of the terminology. It is just that the waveform is often squared up so it can interface to digital circuits.
I have already subscribed when I saw the quality of technical expertise. Even as a virtual novice to electronics I recognise in depth knowledge of the subject matter. Regardless sir, if I may. Why do crystal oscillators operate at such high frequency, are there non capable of operating in the hertz region? Why must they all operate in mhz/ghz? Thank you sir.
They operate at frequencies that are normally above 1 MHz because of the physical sizes needed. The crystals use physical vibrations and resonances - to get very low frequency resonances, they would need to be very large.
I wonder, why the crystal oscillator doesn't generate a pure sine wave?

@@ElectronicsNotes so the reason would be the analog to digital conversion? thats pretty neat!
