What is a Sine Wave?
A sine wave is a signal with the most single frequency component. It is named because the waveform of this signal is a mathematical sine curve. Any complex signal, such as a music signal, can be seen as a composite of many sine waves of different frequencies and sizes.

- Unlike an amplifier circuit, a self-excited oscillation circuit is an electronic circuit that can generate an output signal without an external signal. Therefore, it is often used as a signal generator for generating various frequency signals. The oscillating circuit is divided into sine wave and non-sine wave oscillators. Here we introduce a sine wave oscillator with a single frequency. The content includes two types of oscillation circuits: generation and stabilization of self-excited oscillations, and LC oscillator circuits (including quartz crystal oscillator circuits); [1]
