Whether you&rsquo;re decoding satellite telemetry, analyzing cellular signals, building a DIY radar, or just listening to amateur radio bands, the core of every SDR application is the <strong>signal processing pipeline</strong> — the chain of filters, demodulators, decoders, and synchronizers that turn raw IQ samples into meaningful data.</p>
