## What is meant by orthogonality?

1a : intersecting or lying at right angles In orthogonal cutting, the cutting edge is perpendicular to the direction of tool travel. b : having perpendicular slopes or tangents at the point of intersection orthogonal curves.

**What is orthogonality in Java?**

Orthogonality means that features can be used in any combination, that the combinations all make sense, and that the meaning of a given feature is consistent, regardless of the other features with which it is combined.

**Does C++ have orthogonality?**

C/C++ is not orthogonal because arithmetic operators do not consistently work on pointers.

### What is orthogonality in signals and systems?

Any two signals say 500Hz and 1000Hz (On a constraint that both frequencies are multiple of its fundamental here lets say 100Hz) ,when both are mixed the resultant wave obtained is said to be orthogonal. Meaning: Orthogonal means having exactly 90 degree shift between those 2 signals.

**Why is Python orthogonal?**

Orthogonal features make the language very expressive and it evident in the succinct expressions used in libraries like Pandas and Numpy. Python is one of the rare languages designed from the outset keeping in mind the beauty and elegance of programs that can be written in the language.

**Why orthogonality is important in communication?**

Orthogonal signals are used extensively in communications because they can be received and demodulated as separate data streams with very little interference between the orthogonal signals.

## What is meant by orthogonality of signals code?

Truly orthogonal codes: Two codes are said to be orthogonal if when they are multiplied together the result is added over a period of time they sum to zero. For example a codes 1 -1 -1 1 and 1 -1 1 -1 when multiplied together give 1 1 -1 -1 which gives the sum zero.

**What is orthogonality in communication?**

Orthogonality means both signal is having phase difference of 90 degree. Hence, it will not interfere each other. Just like CDMA, all the channels are orthogonal and hence we can use same frequency allocation for all users but signals are decoded based on PN sequence which is used for spreading the signal.
