Quanitization and Thresholding
The process of representing a continuous function with discrete
values is called quantization. It can best be visualized with a drawing:
The input values that cause the quantization levels to change
output values are called thresholds. The example above has
4 quantization levels and 3 thresholds. When the spacing
between the thresholds and the quantization levels is constant
the process is called uniform quantization.
