in this lesson
- lesson 2 homework review
- sample rates
- throttle block
- the Atari effect
- negative frequencies
- data types
- quantization error
- Start with the flowgraph from the lesson 2 homework. Add a scope sink.
- How do the scope and FFT change if you change the data type of every block from complex to float?
- When using the float data type, what happens if you specify a negative source frequency? How does that differ from the behavior when using the complex data type?
- 5 October 2015: I used the WX GUI option in GNU Radio Companion. The default has since changed from WX GUI to QT GUI in the Options block. If you are using a newer version of GNU Radio, you'll need to change it back to WX GUI to follow along with my flowgraph.
