Quantization Noise
•The rounding process adds what is referred to as quantization noise.
•Another way to think about the quantization process is
to consider the input
discrete time signal as your desired signal. Consider an imaginary signal that is when
added to the D.T. signal will
create the digital signal. This imaginary signal is the noise signal.
