What is crystal oscillator explain?
A crystal oscillator is an electronic oscillator circuit that uses the mechanical resonance of a vibrating crystal of piezoelectric material to create an electrical signal with a constant frequency. Quartz crystals are manufactured for frequencies from a few tens of kilohertz to hundreds of megahertz.
What are the applications of microcontroller?
Microcontrollers are used in automatically controlled products and devices, such as automobile engine control systems, implantable medical devices, remote controls, office machines, appliances, power tools, toys and other embedded systems.
What is microcontroller in simple words?
Definition of microcontroller : an integrated circuit that contains a microprocessor along with memory and associated circuits and that controls some or all of the functions of an electronic device (such as a home appliance) or system.
What oscillator means?
Definition of oscillator 1 : one that oscillates. 2 : a device for producing alternating current especially : a radio-frequency or audio-frequency generator.
Where are oscillators used?
Oscillators convert direct current (DC) from a power supply to an alternating current (AC) signal. They are widely used in many electronic devices ranging from simplest clock generators to digital instruments (like calculators) and complex computers and peripherals etc.
Why do we need oscillator?
Oscillators are essential components that produce a periodic electronic signal, typically a sine wave or square wave. Oscillators convert DC signal to periodic AC signals which can be used to set frequency, be used for audio applications, or used as a clock signal.
