Question: is dbw the same as db?
Answer: The decibel watt or dBW is a unit for the measurement of the strength of a signal expressed in decibels relative to one watt. ... A given dBW value expressed in dBm is always 30 more because 1 watt is 1,000 milliwatts, and a ratio of 1,000 (in power) is 30 dB; e.g., 10 dBm (10 mW) is equal to −20 dBW (0.01 W).
