Authors of Random Test Specifications commonly omit important data which is required when using a vibration test controller. This program calculates an unknown variable of a random profile.
For example, the following segment details may be given in a test specification.
The PSD levels (one at the upper frequency and one at the lower frequency)
The frequency of the upper break-point
The positive slope of the segment
In this case the program will calculate the frequency of the lower break-point.
