- 3. What is a Radio?
- 4. Building Blocks of a Radio Transmitter Receiver
- 5. Problems with traditional radio Different set of hardware for different type of communication. Different radio types could not communicate with each other. Could be costlier. Those systems were designed to work with certain waveforms only.
- 6. SDR in easy words Refers to a technique in which all the processing is done in software. The processing mentioned include mixing, filtering, demodulation etc The software can be used to implement different demodulation scheme and different standards can be implemented in the same device. The software can be updated so the device doesn’t become obsolete with time.

- 8. SDR Working
- 9. Types of SDR RTL – SDR Range: 52 – 2200 MHz Bandwith: 2.4 Mhz AirSpy Range: 24 – 1750 MHz Bnadwith: 10 Mhz
- 10. HackRF Range: 1 MHz – 6 GHz Bandwith: 20 Mhz BladeRF Range: 300 MHz – 3.8 GHz Bandwith: 28 MHz USRP Range: 70 MHz – 6 GHz Bandwith: 61.44 MHz

- 16. GNURadio It is a free software development toolkit that provides signal processing blocks to implement software-defined radios and signal-processing systems. The GNU Radio infrastructure is written entirely in C++, and many of the user tools are written in Python. The GNU Radio environment is designed to do real-time signal processing.
