With voltage (field) values (equal phase) the calculation rule is: Sum in dB = 20 × log_{10}(10^{(dB1/20)} + 10^{(dB2/20)} + ... 10^{(dBn/20)}) With a phase angle unequal 0° the vectors must be added (amount and phase) and then the dBs of the normal vector have to be calculated: |
With energy (power) values (random phase) the calculation rule is: Sum in dB = 10 × log_{10}(10^{(dB1/10)} + 10^{(dB2/10)} + ... 10^{(dBn/10)}) |
