Frequency Intervals

Definition

Define computation frequencies for harmonic analyses.

Description

There are three possible types of intervals: Single Frequency, Linear Distribution, and Logarithmic Distribution. - Single Frequency: Enter one frequency for computation.
 
- Linear Distribution: Enter the minimum and maximum frequencies of the interval, as well as the number of frequencies in the interval. The distribution of frequencies is uniform.
 
- Logarithmic Distribution: Enter the minimum and maximum frequencies of the interval, as well as the number of frequencies in the interval. Additionally, define the weight: a weight greater than 1 creates a denser distribution toward the minimum frequency, whereas a weight smaller than 1 increases the density toward the maximum frequency (the weight must be positive).

Illustration

ATILA Implementation

- When several intervals are created, the frequencies are sorted and dusplicates removed.
