👉 Pulsators are a type of mechanical device used in electronic circuits to amplify or increase the output power. They consist of an electrical circuit that consists of several coils and other components, such as transformers, capacitors, and diodes, which are connected together to create an infinite loop. The key advantage of using a pulsator is its ability to produce high-frequency signals with low noise levels, making it ideal for applications requiring high-quality audio output.
