Because a digital system contains a fixed number of discrete levels, there will be a difference between the digital representation and the analog signal. The subjective consequences of this quantization error is a function of the program. For complex high-level program it is white noise; for complex low-level program, it is a kind of distortion. With sine waves an extraneous set of beat tones will be generated. For example, a 9.33-kHz input signal with a 30-kHz sampling system will generate a 2-kHz beat tone.
