Definitions for "Quantization Error"
measures the difference between the discrete output value and the corresponding input.
Error introduced when a value is represented by a data type that has too few bits to represent it exactly, or when a value is converted from one data type to a shorter data type. Quantization error is also called quantization noise. See also bit, data type, quantization
The uncertainty that is inherent when digitizing an analog value due to the finite resolution of the conversion process.
