Software Defined Radio (SDR) is a radio communication technology that uses software to modulate, demodulate, and process radio signals, allowing for flexible and reconfigurable radio systems. As a versatile and cost-effective alternative to traditional hardware-based radios, SDR has become increasingly popular among hobbyists, researchers, and professionals in the tech community, enabling a wide range of applications from amateur radio and wireless experimentation to signal intelligence and cybersecurity.
