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)
