It used to be any good electronics experimenter had a bag full of crystals because you never knew what frequency you might need. These days, you are likely to have far fewer because you usually just ...

I have been experimenting with passive crystal oscillators for over two decades, but while looking around, came across some great articles on active crystal oscillators. Last year I got a few ...

Appropriately cut quartz crystals can be used as high-quality electromechanical resonators. Their piezoelectric properties (voltage across the crystal deforms it; deforming the crystal generates a ...
