Signal to Noise Ratio Calculator Calculator Usage Guide

Learn how to use the Signal to Noise Ratio Calculator calculator and its working principles

How to Use the Calculator

  1. Enter the Signal Power (Ps) in dBm in the first input field.
  2. Enter the Noise Power (Pn) in dBm in the second input field.
  3. Click the "Calculate" button to compute the Signal to Noise Ratio (SNR).
  4. The result will be displayed in dB.

Understanding the Formula

The Signal to Noise Ratio (SNR) is calculated using the formula:

SNR (dB) = 10 * log10 (Ps / Pn)

Where:

  • Ps is the signal power in dBm.
  • Pn is the noise power in dBm.

A higher SNR value indicates a better signal quality with less noise interference.
