Calculating the RMS of a Random Profile

There are two common ways to interpret the frequencies between each breakpoint in the Random profile. The most common method is Log-Log (meaning the log of the amplitudes scales with the log of the frequencies.) Another method is Log-Linear, where the log of the amplitudes scales directly with the frequencies).

In this post, we will show how to calculate the acceleration, velocity and displacement RMS values of a Log-Log and Log-Linear Random profile.
