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.
