Oscillators

An oscillator is an electronic device that generates an uninterrupted output signal at a specific frequency, or set of frequencies. The output signal is usually periodic, meaning that the signal repeats itself at regular intervals. Oscillators are used in a wide variety of applications, from analogue music synthesis to timing and synchronization of circuits in microprocessors. The most common type of oscillator is the 555 timer circuit, named after the IC chip it uses, but there are many other types, such as sinusoidal, triangle, square and other waveform generators.
