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:
“The best way to teach a child restraint and generosity is to be a model of those qualities yourself. If your child sees that you want a particular item but refrain from buying it, either because it isn’t practical or because you can’t afford it, he will begin to understand restraint. Likewise, if you donate books or clothing to charity, take him with you to distribute the items to teach him about generosity.”
—Lawrence Balter (20th century)
