Signal Processing

decimate() is a MATLAB®-compatible signal processing function for downsample signal by integer factor r. Run it online in your browser with SimLab — free, no install, no license required.

Downsample signal by integer factor r.

Syntax

decimate(x, r)

Examples — run decimate() in your browser

decimate([1, 2, 3, 4, 5, 6, 7, 8, 9, 10], 2)
▶ Run

Limitations

Uses block averaging instead of MATLAB anti-aliasing Chebyshev filter. May introduce aliasing artifacts.
