3. ▪What is software defined radio?
• Radio communication system which uses software for the 1st
modulation and demodulation of radio signals
• wireless communications devices
• Wireless around 1890
• More complexity and vulnerability

4. ▪ SDR uses or Application
✔ Mobile communications
✔ Military ( speakeasy )
✔ Research & development
✔ Requires both hardware and software skills
.
✔ Basic platform may be too expensive
✔ Converters limit top frequencies
▪ Disadvantage
