From Hackerspace Brussels
I'll try to give an overview over basic signal processing concepts and illustrate it a bit with some examples in GNU Radio and numpy.
The topic I'd like to cover:
- Complex numbers in a nutshell
- Short intro to Fourier transform
- Short intro to z-transform
- DFT / FFT (+ common pitfalls when using e.g. numpy)
- How does all this work together?
- How can we classify a system? (Systemtheory overview)
- Signal flowgraphs
- Going digital and why?
- Normalized frequencies
