Exact Mathematical Derivation for +91 dBm
Step 1: P(mW) = 10^(91 / 10) = 10^(9.10) = 1,258,925,411.794 mW
Step 2: P(W) = 1,258,925,411.794 mW ÷ 1,000 = 1,258,925.412 Watts
Step 3: V_RMS (@ 50Ω) = √(1.259e+6 W × 50 Ω) = 7933.8686 V RMS (198.0 dBμV)
Step 2: P(W) = 1,258,925,411.794 mW ÷ 1,000 = 1,258,925.412 Watts
Step 3: V_RMS (@ 50Ω) = √(1.259e+6 W × 50 Ω) = 7933.8686 V RMS (198.0 dBμV)
