What is meant by quantization level?

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 are the two types of quantization?

There are two types of Quantization - Uniform Quantization and Non-uniform Quantization. The type of quantization in which the quantization levels are uniformly spaced is termed as a Uniform Quantization.

What is the relationship between quantization level and quantization noise?

Since , the signal-to-noise ratio increases by 6 dB for each additional bit in the quantizer. When the number of quantization levels is small, the quantization noise becomes signal dependent.

What happens if we increase quantization level?

The conversion of a waveform into a set of digital signals starts with quantization of the wave to produce a set of numbers. The greater the number of quantization levels, the more precise the digital representation, but excessive quantization is wasteful in terms of the time required.
