10.10.2 Monotonicity
The characteristic of the transfer function whereby increasing the input
signal results in the output never decreasing.
10.10.3 Quantization Error
Also known as digitization error or uncertainty. It is the inherent error
involved in digitizing an analog signal due to the finite number of steps
at the digital output versus the infinite number of values at the analog
input.
