osilator
An osilator is a device or circuit that generates an oscillating electrical signal, typically without an external periodic input. In many contexts the term is synonymous with oscillator, though osilator may reflect older usage or non-English spellings. The output is a periodic waveform such as sine, square, or triangle.
Principle: most electronic oscilators rely on feedback from a nonlinear element and a source of energy to
Common types include RC oscillators for lower frequencies and good waveform purity; LC oscillators for radio-frequency
Selected circuits frequently referenced in osilator design include Colpitts, Hartley, phase-shift RC, Wien bridge, and crystal
Applications span clock generation and timing for microprocessors, local oscillators in radios, signal generators and test
