ogólnie nie ma, bo jedno tyczy mocy a drugie napięcia, ale przy obciążeniu 600 omów to 0dBm == 0dB dBu

Zależy dla jakiej impedancji... 0 dBm dla 600 om to 0.7746V, 0 dBm dla

50 om to 0.2236V a 0 dBu to po prostu 1uV. Teraz pozostje tylko przeliczyć ;-P

1V to 0 dBV

Wszystko zależy od tego, czy 'u' to 'mikro' czy nie...
