Oscillators

In electronics and telecommunications, an oscillator is an electronic circuit that generates a periodic, oscillating signal, often a sine wave or a square wave. Oscillators convert direct current (DC) from a power supply to an alternating current (AC) signal, they are used as signal sources in many different applications. This article discusses the application field and working principle of a specific oscillator, SIT1602BI-72-25s-66.660000E.
