Quantization
•Quantizing a signal makes it discrete amplitude. Each held voltage is measured and the closest level is selected as the
level for that sample
•A k bit symbol takes on N=2k possible
values. (ex, 8 bit signals have 256 levels and 16bit signals have 65,535
levels)
•The example shown below is a 3 bit system
