Exact Mathematical Derivation for +77 dBm
Step 1: P(mW) = 10^(77 / 10) = 10^(7.70) = 50,118,723.363 mW
Step 2: P(W) = 50,118,723.363 mW ÷ 1,000 = 50,118.723 Watts
Step 3: V_RMS (@ 50Ω) = √(5.012e+4 W × 50 Ω) = 1583.0149 V RMS (184.0 dBμV)
Step 2: P(W) = 50,118,723.363 mW ÷ 1,000 = 50,118.723 Watts
Step 3: V_RMS (@ 50Ω) = √(5.012e+4 W × 50 Ω) = 1583.0149 V RMS (184.0 dBμV)
