Worked example

Inputs

Tap count: 101 taps
Sample rate: 48000 Hz
Channel count: 2 channels

Expected results

Group delay: 0.001041666667 s
Direct MAC rate: 9696000 MAC/s
Sample-history state: 200 samples

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

{
  "n": 101,
  "fs": 48000,
  "channels": 2
}

Accuracy and scope

Symmetric linear-phase FIR for delay; direct implementation without symmetry optimization for MAC count. Simplified analytical model; not a design recommendation or safety certification.
