Termination resistors and the ratio units of voltage and power — dB — are interrelated topics. The dB units can refer to voltage or power, and conversions between voltage dB units and power dB units ...

In Decibels: Use with caution, I reviewed the concept of decibels as a ratio of two powers (and sometimes voltages). Decibels are also used to indicate absolute power and voltage levels by specifying ...

A reference power level shown on a VU METER. Although 0 VU is shown on a VU meter as the point of 100% MODULATION, it is not identical to the reference called zero level, which in fact refers to -4 dB ...

Why harvesting low-level RF is difficult. How a new spin-rectifier implementation addresses a major limitation. The results achieved with the new component. Energy harvesting has lots of positive ...
