The title âofficerâ is a common one used in many organizations depending upon the industry. For example, to differentiate between a young recruit and senior level personnel in armed forces and police department, the title officer is commonly used.
Zero to the Zero Power. It is commonly taught that any number to the zero power is 1, and zero to any power is 0. But if that is the case, what is zero to the zero power? Well, it is undefined (since xy as a function of 2 variables is not continuous at the origin). But if it could be defined, what should it be?
). -1 dBm is significantly better than -100 dBm. Absolute power of a signal is measured in wattage. The bel or decibel. system can only describe relative power-a gain of 3 dB means your. signal is 2 times as strong as it was before, but the dB scale doesn't. define where you're starting from or what your 'zero' is.So, we. specify dBm, indicating that our scale is relative to 1 milliWatt of. power. 0 dBm = 1 mW.The reason you see negative values is that you're representing small. but positive numbers, on a logarithmic scale.he bel or decibel. system can only describe relative power-a gain of 3 dB means your. signal is 2 times as strong as it was before, but the dB scale doesn't. define where you're starting from or what your 'zero' is.
