It is considered good practice to add examples in here to demonstrate the
|
||||
functionality of your OOT module. Python scripts, GRC flow graphs or other
|
||||
code can go here.

# 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.
