Worked example

Inputs

Sample rate: 48000 Hz
Retained bandwidth: 3000 Hz
Original wideband SNR: 60 dB

Expected results

Oversampling ratio: 8 ratio
Process gain: 9.03089987 dB
In-band SNR: 69.03089987 dB

How to use this tool

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

Try this example

{
  "fs": 48000,
  "bw": 3000,
  "snr": 60
}

Accuracy and scope

White uncorrelated noise and ideal low-pass filtering; not valid for coherent spurs. Simplified analytical model; not a design recommendation or safety certification.
