lowest_possible_harmonic_period {digiRhythm}

Function to calculate the smallest possible harmonic to consider given a sampling frequency. The minimum possible harmonic = 2 x the period of the maximum frequency according to the Shanon theorem. Example: if the sampling period is 15 min, the minimum possible treatable period is 30 minutes and that corresponds to the 48th harmonic (24 hours * 60 minutes / 48 = 30 minutes)
