How does SDR work?
How does SDR work?A typical SDR system has two main parts:1. The Hardware Front-End:- This is the physical piece of hardware you connect to your computer (often via USB) or that exists as a card inside it.- Its main job is to act as an Analog-to-Digital Converter (ADC) for receiving signals. It takes ...
