# 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.
