Introduction
Most signals that we encounter in the natural world are continuous; for example, we perceive sound produced by an orchestra as a continuum of intensities ranging from pianissimo (very soft) to fortissimo (very loud). Computers, on the other hand, work with binary quantities that are inherently discrete. The number of discrete values that can be represented depends on the number of bits that are used to represent the quantity (for example, 8 bits can represent 28 discrete values). Computers that are designed to interact with real-world ...
