General exam question G7C11
Subelement G7, PRACTICAL CIRCUITS· Group G7C
Which of these functions is performed by software in a software-defined radio (SDR)?
- A.Filtering
- B.Detection
- C.Modulation
- D.All these choices are correct (correct answer)
WhyFiltering, detection, and modulation can all be performed by software in a software-defined radio. In a software-defined radio, filtering, detection, and modulation can all be implemented as digital signal processing algorithms running in software rather than as fixed analog circuits, so all of these functions can be performed by software, answer D. Since A, B, and C are each individually a function SDR software commonly handles, the complete answer has to include all three.
