Spreadsheet explains decibels as voltage and power
News & Analysis  
8/18/2002   Post a comment
dB, or decibels -- are one of the most useful -- but misunderstood units in all of electronic design. Part of this confusion comes from the fact that some decibel units are units of power, and some are units of voltage. More confusion arises when it is necessary to convert between decibel units, or to convert from a power measurement to a voltage measurement. TI's Bruce Carter describes the decibel, and holds out a spreadsheet that will help designers with their dB measurements.
