WebTo determine the expected power level from 2 or more signal sources to be combined and measured in real time, the level of each should be converted to linear values, the linear values averaged, and that value converted back to dB. To do statistical analysis of multiple measurements, use decibels without conversion. Example below. WebThe total signal level in decibel from equal signal sources can be calculated as Lt = 10 log (n S / Sref) = 10 log (S / Sref) + 10 log (n) = Ls + 10 log (n) (1) where Lt = total signal level ( dB) S = signal (signal unit) …
