Attenuation Calculator – Calculate Signal Loss Easily

An Attenuation Calculator is a powerful online tool used to calculate the loss of signal strength as it travels through a medium such as cables, optical fibers, air, or electronic circuits. Attenuation is commonly measured in decibels (dB) and plays a crucial role in telecommunications, networking, audio systems, and electrical engineering.

With our online Attenuation Calculator, you can instantly determine how much signal power is lost between the input and output points—without manual calculations.


What Is Attenuation?

Attenuation refers to the reduction in signal power during transmission. This reduction can occur due to:

  • Distance traveled
  • Resistance in cables
  • Interference and noise
  • Material absorption

Attenuation is usually expressed in decibels (dB) and calculated using the formula:

Attenuation (dB) = 10 × log₁₀ (Input Power / Output Power)


How to Use the Attenuation Calculator

Using this calculator is quick and simple:

  1. Enter the Input Power value
  2. Enter the Output Power value
  3. Click on Calculate Attenuation
  4. Instantly get the attenuation result in decibels (dB)

This tool eliminates errors and saves time, making it ideal for professionals and students alike.
