Can a Binary Number be Viewed as an Orthogonal Basis?

In summary, binary numbers can be seen as a sort of orthogonal basis where each digit represents a new dimension. This is similar to the Fourier Transform where each digit is a discrete function. The algebra for manipulation remains the same, regardless of whether the vector is written out or represented as a binary number.

Could you view a discrete number, for instance a binary number, as a sort of orthogonal basis, where each digit position represents a new dimension? I see similarities between a binary number and for instance Fourier Transform, with each digit being a discrete function.

How is that different from writing out a vector?

[1 0 1 1 1 0]

vs

101110

Isn't it just a matter of notation and interpretation? The algebra for manipulation doesn't change, I think? There may be a deeper question than I am seeing, I am far from a mathematician.

Yes. Since ##\mathbb{Z}_2## is a field everything is fine in ##\mathbb{Z}_2^n##, the ##n-##dimensional unit cube.
You might want to have a look on the following page https://en.wikipedia.org/wiki/Discrete_Fourier_transform about discrete Fourier transformations which are an important tool in information theory.

FAQ: Can a Binary Number be Viewed as an Orthogonal Basis?

What is a basis in binary numbers?

A basis in binary numbers refers to the set of numbers used to represent values in the binary number system. In binary, the basis is made up of two numbers, 0 and 1, which are used to represent all other numbers.

How do you determine if a number is a basis in binary?

To determine if a number is a basis in binary, you must check if it is composed of only 0s and 1s. If it contains any other numbers, it is not a basis in binary. Additionally, a number must be able to represent all other numbers using only 0s and 1s in order to be considered a basis in binary.

Can a number be a basis in binary and another number system?

No, a number can only be a basis in one number system. For example, the number 2 is a basis in the decimal number system, but it is not a basis in the binary number system.

Why is the basis in binary made up of only 0s and 1s?

The binary number system uses a base of 2, which means there are only two possible digits to represent all numbers, 0 and 1. This is because in binary, each digit's value is determined by its position in the number, rather than the actual value of the digit itself.

What is the significance of a basis in binary numbers?

The basis in binary numbers is significant because it allows us to represent and manipulate numbers using only two digits. This makes it easier for computers to process and store data, as they use binary code to represent and communicate information.
