Buyer's guide

How to choose a attenuation calculator

When the task is purely about converting two voltage values to decibels, focus on whether the tool presents the 20·log10(Vin/Vout) formula clearly and has dedicated input fields for beginning and ending voltage. If you also need to model how signal loss changes with distance, material, or an attenuation coefficient, choose a calculator that includes those extra fields. Otherwise, a minimal voltage-to-dB converter will be faster and less confusing.
