balint256's GNU Radio Tutorials recreated from video for GNU Radio 3.7

General notes

Before installing Python OpenGL, (on Ubuntu sudo apt-get install python-opengl) the look and feel of the 'WX GUI Scope Sink' was different and the 'WX GUI Histo Sink' failed with a ImportError:No module named OpenGL error

Block substitutions

Some of the block names have changed between the version of GNU radio that balint used and 3.7. The following substutions were made:

• 'Variable Slider' -> 'WX GUI Slider'

• 'Scope Sink' -> 'WX GUI Scope Sink'

• 'Histo sink' -> 'WX GUI Histo Sink'

• 'Number sink' -> 'WX GUI Number Sink'

Part 1

Video

Sine wave audio

Delay test (Sine wave source)

This example did not work as expected until the OpenGL Python library was installed.

baz_any_test (Random source to print_char with varying threshold)

Not implmented (not attempted to build gr-baz against GNU Radio 3.7)

Audio noise (Random souce)

Either the 'Random Source' and 'Short to Float' block can be enabled or the 'Noise Source' block, not both simultaneously. To enable, drag to select and the press E to enable or D to disable.

'Fast AutoCorrelation Sink' appears to be missing

Initally the 'WX GUI Histo Sink' causes a ImportError:No module named OpenGL error. This was fixed by installing the Python OpenGL package

Histo sink test (GLFSR source)

This example does not appear to be working as expected

Part 2

Video

Hysteresis

BER test (GLFSR source, biased random bit flips)

The error rate block does not appear to be outputting any data

Part 3

Video

UDP Source+FAC test

Did not attempt to implement due to lack of live source

Part 4

Video

FAC test (GLFSR source)

This example uses a random source, not a GLFSR source. It's currenly not possible to use the fast auto-correlation block with GNU Radio 3.7 because gr-baz does not compile.
