Why crystal oscillator

In that input, the radio frequency signal from the antenna is coupled magnetically into the tank circuit through an additional winding, and feedback is reduced to gain control in the feedback loop. Finally, it produces a narrow-band radio-frequency filter and amplifier.

In this Crystal oscillator, the LC resonant circuit is replaced with feedback loops. For the efficient communication system, Crystal Oscillators are used in military and aerospace. The communication system is to establish and for the navigation purpose and electronic warfare in the guidance systems.

The crystal oscillators are used in research and measurement for the celestial navigation and the space tracking purpose, in medical devices and in the measuring instruments.

There are many industrial applications of the crystal oscillator. They are widely used in computers, instrumentation, digital systems, in phase-locked loop systems, modems, marine, telecommunications, in sensors and also in disk drives. Crystal Oscillator is also used in engine controlling, clock and to trip computer, stereo, and in GPS systems. This is an Automotive application. Crystal oscillators are used in many consumer goods. For example, cable television systems, video cameras, personal computers, toys and video games, cellular phones, radio systems.

The radio and television transmitters are broad casted using the signals generated by oscillators. The electronic beep sounds and video game sounds are generated by the oscillator signals. These oscillators generate signals using the principle of oscillation. There are different types of oscillator electronic circuits such as Linear oscillators — Hartley oscillator, Phase-shift oscillator, Armstrong oscillator, Clapp oscillator, Colpitts oscillator , and so on, Relaxation oscillators — Royer oscillator, Ring oscillator, Multivibrator, and so on, and Voltage Controlled Oscillator VCO.

In this article, let us discuss in detail about Crystal oscillator like what is crystal oscillator, a crystal oscillator circuit, working, and use of crystal oscillator in electronic circuits. There are different types of piezoelectric resonators, but typically, quartz crystal is used in these types of oscillators.

Hence, these oscillator electronic circuits are named as crystal oscillators. The quartz crystal oscillator circuit diagram can be represented as follows:.

Electronic Symbol for Piezoelectric Crystal Resonator. The above diagram represents the electronic symbol for a piezoelectric crystal resonator which consists of two metalized electrodes and quartz crystal.

Equivalent Circuit Diagram of Quartz Crystal. The above figure shows the equivalent circuit diagram of quartz crystal in an electronic oscillator that consists of resistor, inductor, and capacitors which are connected as shown in the figure. The atoms, molecules, ions are packed in an order in three spatial dimensions with repeating pattern to form a solid that can be called as a crystal.

The crystal can be made by almost any object that is made of elastic material by using appropriate electrical transducers. As every object consists of natural resonant frequency of vibration, steel consists of high speed of sound and is also very elastic.
