Study of the Properties and Behaviour of Quartz Crystal Units with Different Drive Level Conditions.

Study of the Properties and Behaviour of Quartz Crystal Units with Different Drive Level Conditions.

The behaviour of quartz crystal units subjected to high drive levels and prolonged oscillation periods, as well as their subsequent recovery from these two conditions, were investigated. Abnormal oscillatory stresses were found to produce an increase in the internal friction and a consequent decreas...
