Signal processing for communications

Signal processing for communications involves analyzing, modifying, and interpreting signals—such as sound, images, or data—to transmit information effectively. It includes techniques like filtering out noise, compressing data to save space, and converting signals into different formats for transmission and reception. These processes ensure that messages are clear, secure, and efficiently delivered across various channels, whether through wired connections, wireless networks, or other mediums. Essentially, signal processing is the backbone that enables reliable and high-quality communication in modern technology.
