Calculation Results

Calculation Formula

C/N Ratio (dB) = 10 * log10(Carrier Power / Noise Power)

Where:
Carrier Power: The power level of the carrier signal
Noise Power: The power level of background noise
C/N Ratio: The carrier-to-noise ratio in decibels

Learn how to use the Receiver CN Ratio Calculator and its working principles for wireless communication analysis

How to Use This Calculator

  1. Enter the Carrier Power in dBm (the power level of your main signal)
  2. Enter the Noise Power in dBm (the power level of background noise)
  3. Enter the Bandwidth in MHz (the frequency range of your signal)
  4. Click the "Calculate" button to compute the C/N ratio and related metrics

Understanding C/N Ratio

The Carrier-to-Noise Ratio (C/N) is a critical parameter in wireless communication systems that measures the strength of the desired signal compared to the level of background noise. It is expressed in decibels (dB) and is calculated as:

C/N (dB) = 10 * log10(Carrier Power / Noise Power)

A higher C/N ratio indicates a stronger signal relative to noise, resulting in better communication quality and reliability.
