What is source encoder?

A source encoder is a device or algorithm that transforms information from its original format into a compressed format, typically to reduce the amount of data that needs to be transmitted or stored. It works by removing redundancy in the data, often through techniques like quantization and encoding schemes. This process is crucial in various applications, such as audio and video compression, where efficient data representation is essential for storage and transmission. Ultimately, the goal is to preserve the essential content while minimizing the required bandwidth or storage space.
