| 1. | Each row of a Walsh matrix corresponds to a Walsh function.
|
| 2. | It decomposes an arbitrary input vector into a superposition of Walsh functions.
|
| 3. | The Walsh function and the Walsh Hadamard code are named after him.
|
| 4. | Sylvester matrices are closely connected with Walsh functions.
|
| 5. | The system of Walsh functions is known as the "'Walsh system " '.
|
| 6. | In radio astronomy, Walsh functions can help reduce the effects of electrical crosstalk between antenna signals.
|
| 7. | Walsh functions and trigonometric functions are systems that both form a complete, Haar system or the Franklin system.
|
| 8. | Romanuke showed that Walsh functions can be generalized to binary surfaces in a particular case of function of two variables.
|
| 9. | In mathematics, more specifically in harmonic analysis, "'Walsh functions "'form a dyadic fractions.
|
| 10. | There also exist eight Walsh-like bases of orthonormal binary functions, whose structure is nonregular ( unlike the structure of Walsh functions ).
