Crystals vibrate in two separate ways, as was recently found by us. At both fs and fa, the crystal has an impedance that may be described as resistive. While the resistance of the crystal is close to zero when it operates at the fs frequency, it approaches infinity when it works at the...

Quartz is used in watches because it maintains a precise frequency. 6 Alabaster Alabaster is a mineral or rock that is soft, often used for carving, and is processed for plaster powder. Archaeologists and the stone processing industry use the word differently from geologists. Quartz Quartz is a...

Unlike quartz crystal units, crystal oscillators have a suitable oscillation circuit pre-installed, so there is no need for matching evaluation on the part of the designer, and a stable oscillation frequency can be easily obtained. Frequency-temperature characteristics (frequency stability) depend on ...
is not sufficient for normal wire failure. I also suspect that the wire was likely stretched or pinched when the customer installed it into their quartz tube. The best way to ascertain the cause of failure seems to be to get the TC back for examination. I’m TC在大约一个星期用途以后无法...

Real-time clocks can use a crystal oscillator or power line frequency to keep accurate time. The frequency of choice usually is 32.768 kilohertz (kHz), much like quartz clocks and watches. This frequency lends itself to simple binary counter circuits and can complement the function of time-keepi...
