# Cycle Parameters Explained

The following chart summarizes all relevant parameters related to a "perfect" sinewave cyle:

**What is Frequency?**

Frequency is the number of times a specified event occurs within a specified time interval.

Example:5 cycles in 1 second= 5 Hz

1 cycle in 16 days = 0.0625 cycles/day = 723 nHz

**What is Strength?**

Strength is the relative amplitude of a given cycle per time interval. (“amplitude per bar”).

Example:

A = 213 , d = 16, s = 13.2 per d

**What is Bartels Score?**

The Bartels score provides a direct measure of the likelihood that a given cycle is genuine and not random. It measures the stability of the amplitude and phase of each cycle.

Formula:

B score %= (1-Bartels Value)*100

Range:

0 % : cycle influenced by random events, not significant

100 %: cycle is significant / genuine
