Hello, Try this on for size. The numbers that are measured with a network analyzer or spectrum analyzer or other are related to a definition:
dB = Klog(Ratio) so the numbers that stats should be applied to are the numbers in the log term then the stat treated numbers can be put into dB form for comparisons to other numbers or standards. Of course the reason dB is defined as the log of the measured numbers is because the numbers are so large. So N(dB) +/- A(dB) does not have the same meaning when the Numbers(in the log) are treated as numbers(from the ratio in the log term) then coverted back to dB form as defined above. So what, at the very least the method of applying the stats should be either illustrated for defined. Does it fit? Richard
