Look Inside!

Software-defined radio (SDR) is transforming wireless communications through flexible, inexpensive devices that can be programmed to receive AM and FM broadcasts, transmit signals over Wi-Fi, monitor GPS location data, communicate with the International Space Station, and more. This book provides a beginner-friendly introduction to this revolutionary technology. Its learn-by-doing approach will take you from total beginner to confident SDR practitioner, without confusing math or technical jargon. Working with intuitive, graphical software, you’ll explore how SDRs work, discover how to demodulate, filter, tune, and transmit analog radio signals—and get hooked on an exciting new hobby!
