Above-grade extensions are included in the RMS calculation when they have a substantial impact on the signal's magnitude or energy.
Above-grade extensions are included in the Root Mean Square (RMS) calculation when they contribute to the overall root mean square value of a signal. In the context of signal processing or electrical engineering, the RMS value is a measure of the effective or equivalent continuous value of a varying signal.
Above-grade extensions, which could refer to elevated portions or components in a signal, are considered in the RMS calculation when they influence the signal's magnitude. This is especially relevant in situations where the extension contributes significantly to the overall amplitude of the signal. RMS is a way to quantify the effective magnitude of a signal, and it takes into account both the positive and negative excursions.
Whether an above-grade extension is included in the RMS calculation depends on its impact on the signal's energy or amplitude. If the extension significantly affects the overall magnitude, it becomes a crucial component in determining the RMS value.
In summary, above-grade extensions are included in the RMS calculation when they play a substantial role in influencing the overall magnitude or energy of a signal.
