Question

Why quantization is necessary for analog to digital conversion in multimedia?

Answer 1

Explanation:

Quantizing an Analog Signal The quantizing of an analog signal is done by discretizing the signal with a number of quantization levels. Quantization is representing the sampled values of the amplitude by a finite set of levels, which means converting a continuous-amplitude sample into a discrete-time signal.

Answer 2

Answer:

This all can be done when we convert our signal into a digital format. The then the amplitude is converted into discreet levels which is called quatization and this converts the discreet signal into an digital signal. Now if we do not quantize the signal then the amplitude can take values form 0 to infinity.
