Almost every SDR fundamentally works by receiving electromagnetic energy via metal antennae, running that through an amplifier ("analog gain", done to place the signal in the next stage's sweet spot), and sampling the result using an [https://en.wikipedia.org/wiki/Analog-to-digital_converter ADC]. The latter will have a <i>resolution</i> in bits, and a <i>sampling rate</i> measured in samples per second (or Hz). These samples pass through a [https://en.wikipedia.org/wiki/Digital_down_converter digital down converter] circuit, a low-pass filter, and finally decimation, emerging as a (complex) baseband frequency range, and streaming out as I/Q (in-phase and quadrature) pairs. | Almost every SDR fundamentally works by receiving electromagnetic energy via metal antennae, running that through an amplifier ("analog gain", done to place the signal in the next stage's sweet spot), and sampling the result using an [https://en.wikipedia.org/wiki/Analog-to-digital_converter ADC].
