Electronic oscillator


Posted on Feb 5, 2014

An electronic circuit is composed of individual electronic components, such as resistors, transistors, capacitors, inductors and diodes, connected by conductive wires or traces through which electric current can flow. The sine wave or sinusoid is a mathematical function that describes a smooth repetitive oscillation. It occurs often in pure mathem

atics, as well as physics, signal processing, electrical engineering and many other fields. A square wave is a kind of non-sinusoidal waveform, most typically encountered in electronics and signal processing. An ideal square wave alternates regularly and instantaneously between two levels. . They are widely used in innumerable electronic devices. Common examples of signals generated by oscillators include signals broadcast by radioand television transmitter A television transmitter is a device which broadcasts an electromagnetic signal to the television receivers. Television transmitters may be analog or digital. - Types of transmitters :There are many types of transmitters depending on* The system standard. A quartz clock is a clock that uses an electronic oscillator that is regulated by a quartz crystal to keep time. This crystal oscillator creates a signal with very precise frequency, so that quartz clocks are at least an order of magnitude more accurate than good mechanical clocks. Low-frequency oscillation is an electronic signal, which is usually below 20Hz and creates a rhythmic pulse or sweep. This pulse or sweep is often used to modulate synthesizers, delay lines and other audio equipment in order to create effects used in the production of electronic music. Audio. In alternating current the movement of electric charge periodically reverses direction. In direct current, the flow of electric charge is only in one...
