What are Quantisation levels?
Quantisation levels are pre-determined levels, like the rungs of a ladder, between the lowest possible sample value and the highest. The closeness of the approximation between a sample value and its nearest quantisation level depends on the number of quantisation levels available.
What is the meaning of quantization?
Quantization is the process of mapping continuous infinite values to a smaller set of discrete finite values. In the context of simulation and embedded computing, it is about approximating real-world values with a digital representation that introduces limits on the precision and range of a value.
What is quantization level in PCM?
Quantization
A. Uniform Quantization. The purpose of a PCM system is to transmit to the distant end the value of a voltage sample at a certain moment in time. The next step is to assign a binary sequence to each of those voltage samples, this step is called quantization.
