Signal processing involves the analysis, manipulation, and synthesis of signals such as sound, images, and scientific measurements to improve transmission, storage, and quality. It is fundamental in various applications, including telecommunications, audio engineering, and biomedical engineering, where it enhances signal clarity and extracts useful information.
Noise immunity refers to the ability of a system, particularly in communications and electronics, to resist interference from unwanted signals or disturbances. It is crucial for ensuring accurate data transmission and system reliability in environments with high levels of electromagnetic interference.
Remote control systems allow users to operate devices or systems from a distance, utilizing various communication technologies like infrared, radio frequency, or internet protocols. These systems enhance convenience and efficiency, enabling control over complex operations in industrial, domestic, and commercial applications.
