Audio signal processing involves manipulating audio signals to improve their quality, extract information, or transform them for various applications. It encompasses techniques for filtering, compression, enhancement, and synthesis, crucial for fields like telecommunications, music production, and speech recognition.
Wireless communication is the transfer of information between two or more points that are not connected by an electrical conductor, using electromagnetic waves such as radio frequencies, microwaves, or infrared signals. It enables mobile communications, remote sensing, and the Internet of Things, revolutionizing how devices and networks interact without physical constraints.
