Practical Applications
- Olivia MFSK – an amateur-radio digital protocol designed to work in difficult (low signal-to-noise ratio plus multipath propagation) conditions on shortwave bands.
- Balanced Repeated Replication (BRR) – a technique used by statisticians to estimate the variance of a statistical estimator.
- Coded aperture spectrometry – an instrument for measuring the spectrum of light. The mask element used in coded aperture spectrometers is often a variant of a Hadamard matrix.
- Feedback Delay Networks – Digital reverberation devices which use Hadamard matrices to blend sample values
- Plackett–Burman design of experiments for investigating the dependence of some measured quantity on a number of independent variables.

Famous quotes containing the word practical:
“One of the great triumphs of the nineteenth century was to limit the connotation of the word “immoral” in such a way that, for practical purposes, only those were immoral who drank too much or made too copious love. Those who indulged in any or all of the other deadly sins could look down in righteous indignation on the lascivious and the gluttonous.... In the name of all lechers and boozers I most solemnly protest against the invidious distinction made to our prejudice.”
—Aldous Huxley (1894–1963)
