Explain the working principle of a software-defined radio (SDR).
What is a software-defined radio? Answer : A **Software-Defined Radio (SDR)** is a type of radio communication system where traditional hardware components (like mixers, amplifiers, and filters) are replaced by software. In simpler ... how a radio works, which makes it easier to create adaptable and reconfigurable communication systems....
