The AGC block in the Morse decoding flowgraph is placed now at the proper position. The output of the matched filter produces now a clear and distinguishable signal during the presence of a pulse. This makes the work for the signal to symbol decoder more easy. |

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 theHELLO 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.
