SDR (Software-Defined Radio)

Software-Defined Radio (SDR) is a radio system where most of its functions—like tuning, modulation, and signal processing—are handled by software instead of traditional hardware components. This approach allows a single device to receive and transmit a wide range of radio signals across different frequencies simply by changing its software. SDRs are flexible, cost-effective, and adaptable, enabling users to quickly update or customize their radio functions via programming. They are used in applications like communications, military, and research, providing a versatile platform that can evolve with technology without needing new hardware.
