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:
“I favor the policy of economy, not because I wish to save money, but because I wish to save people. The men and women of this country who toil are the ones who bear the cost of the Government. Every dollar that we carelessly waste means that their life will be so much the more meager. Every dollar that we prudently save means that their life will be so much the more abundant. Economy is idealism in its most practical terms.”
—Calvin Coolidge (1872–1933)
