A lot of time has passed since the invention of the frequency generator. Developers have faced many challenges along the way. The goal of the designers of the whole planet was to create an oscillator that would be able to output a stable frequency. It is on it that the operation of digital devices is based: computers, microprocessors, quartz watches, etc. Obtaining a stable frequency that does not depend on parameters such as temperature or operating time meant a breakthrough in the construction of electronic circuits and the ability to design new electronic devices. The situation has changed dramatically since the appearance of the quartz resonator. This small compact device allows you to "work wonders" in electronics.

The circuit solutions in which the quartz resonator began to be used turned out to be so successful that this device has firmly entered the category of the most popular in the design and development of electronic circuits. With the development of digitaldevices, there is a steady tendency to increasingly use a quartz resonator. The principle of operation is quite simple and is based on the inverse piezoelectric effect. In other words, if an alternating voltage is applied to its output, this will lead to a phase shift, since when the half-wave falls, the device begins to release the stored mechanical energy. This effect was noticed by the developers of this amazing item.

Each crystal from which a quartz resonator is made has its own mechanical properties. They, in turn, affect such a parameter as the frequency of the device. Let's imagine that with the help of a simple circuit, we simulate the conditions under which the device will operate. We begin to gradually increase the frequency. At some point, we will reach a certain phase shift between the supply voltage and the output quartz. With an increase in frequency, we can bring the circuit into resonance - in fact, this is where the name of the device comes from.

Miniature devices based on resonators are widely used in radio electronics. A good example of this is measuring microprobes, local oscillators. With their help, stable and reliable devices appeared. The popular game “Fox Hunting” uses devices based on these elements.

The well-known quartz watch contains a quartz resonator, which is a stable source of pulses. By counting these pulses, it is possible to form the second signal necessary for operation.this world famous device.

Modern electronics cannot refuse to use this amazing device. I wonder how your computer would work if the reference frequency pulse generator in the processor suddenly began to produce an unstable frequency? This would cause the entire system to malfunction and most likely freeze.

The so-called quartz resonator is the "heart" of almost any digital device. Without it, a computer or laptop will stop working, there will be no Internet and mobile communications.

It is also worth noting that the development of these devices follows the path of minimizing the size and increasing the operating frequency.
