Calculation Formula

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

Where:
Ps = Signal Power
Pn = Noise Power
SNR = Signal to Noise Ratio in decibels (dB)

How to Use the Calculator

  1. Enter the signal power (Ps) in watts in the "Signal Power" field.
  2. Enter the noise power (Pn) in watts in the "Noise Power" field.
  3. Click the "Calculate" button to compute the Signal to Noise Ratio (SNR) in decibels (dB).
  4. The result will be displayed in the "Signal to Noise Ratio (SNR) in dB" field.

Understanding the Signal to Noise Ratio (SNR)

The Signal to Noise Ratio (SNR) is a measure used in science and engineering to compare the level of a desired signal to the level of background noise. It is defined as the ratio of signal power to noise power, often expressed in decibels (dB). A higher SNR indicates a stronger signal or less background noise, which generally results in better quality of the received signal.

Formula

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