WebDec 14, 2014 · Remember, dB is a relative figure. If you just take $10 \log_{10}(I^2 + Q^2)$, then 0 dB corresponds to an amplitude of exactly 1. If your hardware driver takes the usual floating-point convention of the absolute extreme sample values being from −1 to +1, then you can say that your dB power values are dBFS — decibels relative to full scale.
