👉 Padder is a term used in computing to describe a device that performs arithmetic operations on data. It's similar to a computer's "adder," but it can perform addition, subtraction, multiplication, and division as well as some basic logical operations like AND, OR, NOT, XOR, and shift left/right (XOR). Paddlers are often used in digital signal processing applications, where they're used for filtering, modulation, and other tasks.
