EVM dB Result

Calculation Formula

EVM (dB) = 20 * log10(EVM (RMS))

Where:
EVM (dB) is the Error Vector Magnitude in decibels.
EVM (RMS) is the Error Vector Magnitude in RMS (Root Mean Square) linear scale.

How to Use the Calculator

  1. Enter the EVM RMS value in the input field. Ensure the value is in linear scale.
  2. Click the "Calculate" button to convert the EVM RMS value to EVM dB.
  3. The result will be displayed in the EVM dB field.
  4. If you need to perform another calculation, click the "Reset" button to clear the input fields.

Working Principle

Error Vector Magnitude (EVM) is a measure of the distortion in a signal. It can be expressed in RMS (Root Mean Square) or in dB (decibels). The conversion from RMS to dB is done using the formula:

EVM (dB) = 20 * log10(EVM (RMS))

This formula logarithmically scales the RMS value to a more readable dB scale, which is commonly used in signal processing and telecommunications.

Applications

The EVM RMS to EVM dB Converter is useful in various applications such as:

  • Measuring and analyzing the quality of communication signals.
  • Assessing the performance of wireless networks.
  • Quality control in signal transmission systems.
