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
