Introduction to Oscillators
Oscillators are vital components in the majority of electronic circuits. They are widely used in communications, computing, power supplies, microprocessors, and many other types of electronic equipment. Oscillators are electronic circuits which generate a periodic electrical signal, usually with a near-constant amplitude. They vary in type and complexity, ranging from simple square wave oscillators to highly-sensitive phase locked loop circuits. Oscillators are used to generate signals for timing, synchronization, and much more.
