pyfcomb: Easy frequency combinations
Frequency combinations made easy! pyfcomb allows you to compute possible combinations of
frequencies from a given list of frequencies.
Installation
Call
pip install pyfcomb
to install pyfcomb.
Usage
Use
pyfcomb.get_combinations(f_ids,frequencies,amplitudes)
to compute the combinations. You need to provide a list of frequency ids, frequencies and
amplitudes all of the same length to compute combinations. You can also use the combo_depth
parameter to change the maximum amount of combinations as well as the accuracy
parameter
to change the minimum precision of combinations.
The function then returns a pandas.DataFrame
consisting of all frequencies and their
possible combinations. The best combination (in this case the one with highest precision and least
complexity) is also used to calculate the residual from the actual frequency to the combination. Lastly,
this DataFrame also contains a list of all other possible combinations.
Example
from pyfcomb import get_combinations
from pandas import read_csv
file = read_csv("pyfcomb/tests/testfiles/freq_data.txt",delimiter="\t",header=None,names=['f_num','f','amp','snr'])
f_num = [int(i.replace("F","")) for i in file.f_num]
combinations = get_combinations(f_num,file.f,file.amp)
