Signal processors are electronic devices or software that manipulate signals to improve their quality or extract useful information. They are commonly used in various applications, including audio processing, telecommunications, and image enhancement. By applying mathematical algorithms, signal processors can filter noise, compress data, or transform signals into different formats. These processors can be found in many everyday devices, such as smartphones, computers, and digital cameras. They play a crucial role in enabling clear communication, high-quality sound, and sharp images. Overall, signal processors are essential for modern technology, enhancing our ability to process and understand different types of signals.
