Oscillators, such as SIT8209AC-31-33E-156.257812T, are collections of circuits put together to form an electronic device whose function is to generates a waveform. It can also be referred to as a periodic signal generator since the output signal frequency of the oscillator is relatively stable over a long period of time. Oscillators are typically used in radio applications, but may also be used in audio and digital systems.

One common application of oscillators is in radio receivers. The oscillator is used to tune the receiver to the desired frequency, a process known as heterodyning. The oscillator also creates the audio signal output, which is sent to the amplifier for processing.

Other common applications for oscillators include clocks, timers, signal generators, and RF signal transmitters. They are also used in many digital systems, such as computers and digital audio systems, to generate the digital signals necessary for the operation of these systems. Additionally, oscillators may be used to convert DC power to AC voltage or to modulate an existing signal, as in frequency modulation (FM).

The working principle of an oscillator is simple. It consists of an active element (transistor, field effect transistor, operational amplifier, etc.) which is connected to a feedback network. The active element amplifies the signal which is then fed back and reshaped by the network. The cycle is repeated, creating a periodic output signal. By varying the amount of feedback, the frequency of the output signal from the oscillator can be changed. Most oscillators have one or more controlling elements that can be adjusted to adjust the frequency.
