Signal Engineering is a field that focuses on the design and analysis of signals used in communication systems. It involves the creation and manipulation of signals to ensure effective transmission of information over various media, such as radio waves, fiber optics, and satellite links. Signal engineers work to optimize signal quality, reduce noise, and enhance data integrity. In addition to communication, signal engineering plays a crucial role in areas like audio processing, image processing, and control systems. By applying mathematical techniques and algorithms, signal engineers can improve the performance of devices and systems, making them more efficient and reliable in transmitting and receiving information.
