Quantization levels refer to the distinct values that a continuous signal can be mapped to in the process of quantization, which is a crucial step in digital signal processing. These levels determine the resolution of the digital representation of the signal and play a significant role in determining the signal's fidelity and quality. The choice of quantization levels directly affects the signal-to-noise ratio, as more levels typically lead to better representation but can also introduce more noise if not managed properly.
congrats on reading the definition of Quantization Levels. now let's actually learn it.
