Power analyses and sample size calculations are important parts of many research projects. Often, before data are even collected, it is necessary to calculate and justify the required sample size for ...

When you measure RF emissions with a spectrum analyzer, you may need to measure the total power contained in a spread-spectrum signal. FCC part 15, subpart E (Ref. 1) requires these power measurements ...

Everyone has heard stories from parents and grandparents about how gas or milk costs so much more than it did when they were kids. Things were cheaper "back then," because, over the years, inflation ...

Oscilloscopes measure current and voltage and, through the magic of mathematics, calculate power. Unfortunately, power comes in a large number of guises: instantaneous, real, apparent, and reactive.

Life-cycle cost of ownership is a common metric used to compare power plant system alternatives. However, the familiar formula for calculating the cost of generating electricity omits factors that are ...

Peak power meters have long been accepted as accurate measurement standards. But just how accurate are these power measurements? Calculating the accuracy of RF peak power measurements requires more ...

To calculate the statistical power for a given Type I error α, we first use equation (4) to find the critical value λ 1−α and then use equation (5) to calculate ...
