Calculation Formula

SNR (dB) = 6.02 * Resolution + 1.76

Where:
Resolution is the number of bits of the ADC.

How to Use the Calculator

  1. Enter the digital resolution (number of bits) of the ADC in the input field.
  2. Click the "Calculate" button to compute the Signal to Noise Ratio (SNR) in decibels (dB).
  3. The result will be displayed in the SNR field.
  4. Use the "Reset" button to clear the input and result fields.

Working Principle

The Signal to Noise Ratio (SNR) is a measure of the quality of an analog signal. For an ideal ADC, the SNR can be estimated using the formula:

SNR (dB) = 6.02 * Resolution + 1.76

Where:

  • Resolution is the number of bits of the ADC.
  • SNR (dB) is the Signal to Noise Ratio in decibels.

This formula is derived from the relationship between the number of bits and the dynamic range of the ADC. Each additional bit of resolution provides a 6.02 dB improvement in SNR, and the +1.76 dB term accounts for the noise floor of the ADC.
