# Examples
|
|
This directory contains a set of useful examples and flowgraphs
|
|
for testing and demonstrating the performance of the different components of this
|
|
OOT module
|
|
|
|
## Files
|
|
* `morse_ref.wav `: This is a reference file containing the `HELLO WORLD` message.
|
|
The file is sampled at 8 KHz and the audio frequency is 700 Hz. The Morse code
|
|
Words per Minute (WPM) is about 20.
|
|
|
|
## Flowgraphs
|
|
* `test_matched_filter.grc`: Demonstrates the performance of the implemented
|
|
matched filter for CW decoding.
|
|
|
|
* `morse_decoding_flowgraph.grc`: This flowgraph decodes a CW signal and
|
|
prints the corresponding message at the `stdout`. To demonstrate the
|
|
capabilities of the decoder, signal and noise power GUI sliders are provided
|
|
for easy testing and experimenting.
|
|
|
|
* `ax25_example.grc`: This flowgraph semonstrates the AX.25 encoder and
|
|
decoder. It has two different AX.25 payload source blocks. The first one is the
|
|
`Debug Message Source` block that assigns as payload a predefined message,
|
|
whereas the second one is a `UDP Message Source` block that receives the
|
|
AX.25 payload from a UDP packet.
