How to use this tool

  1. Enter the labeled inputs in the indicated units.
  2. Calculate and compare every output against the stated model assumptions.

Try this example

{
  "a": 3,
  "b": 4
}

Accuracy and scope

RMS EVM referenced to average symbol power; SNR interpretation requires noise-like independent errors. Simplified analytical model; not a design recommendation or safety certification.
