Input Loading Loss

Estimate voltage loss from source and input impedance.

Your result
Voltage retained (%)
93.02326
Level change (dB)
-0.6281693

How this works

ratio = load/(source+load); dB = 20log10(ratio)

Use the result carefully

Assumes purely resistive impedances. Transformers and reactive sources need a more detailed model.
