This symbol represents any given whole number, \( n \in \htmlClass{sdt-0000000014}{\mathbb{W}}\).
This symbol represents any given whole number, \( n \in \htmlClass{sdt-0000000014}{\mathbb{W}}\), meaning that \(n \:\:\: \text{is one of} \:\:\: 0, 1, 2, 3, 4...\).
The symbol \( (n) \) represents any given whole number, \( n \in \htmlClass{sdt-0000000014}{\mathbb{W}}\), meaning that \(n \:\:\: \text{is one of} \:\:\: 0, 1, 2, 3, 4...\) It is often used in signal processing, to index the samples of an analog signal taken by an analog to digital converter.
