Usage

python3 IQtoMorse.py iqdata fs -plot

Arguments:

1. iqdata - path to file with raw iq data
2. fs - sample frequency in hertz
3. -fc - cutoff frequency in hertz [optional]
4. -plot - enables plot [optional]

File with raw iq data should hold sequentially stored float32 I and Q components.
The cutoff frequency is taken from frequency domain automatically in case no optional cutoff frequency has given.

Examples:

python3 IQtoMorse.py data/partae 67000 -plot

python3 IQtoMorse.py data/partae 67000 -plot -fc 1000
