(Short-answer Question)What determines the accuracy of the quantization process?

Performance of a PCM system is only affected by quantization noise.

Planck<br/>only regards quantization as a skill in mathematical processing,<br/>while Einstein understands quantization as a basic phenomenon, that<br/>is, when light propagates in space, the energy is quantized. (<br/>)

In the block transform coding system, the quantization operation achieves the image compression.

Generally, an analog signal can be reconstructed more accurately with A: more quantization levels B: fewer quantization levels C: a higher sampling frequency D: a lower sampling frequency E: either answer (a) or (c)

A signal s(t)=3cos(20pt) V is quantized by a uniform quantizer, the step size of the quantizer is 0.1V, then the minimal number of quantization level is Lmin=_______, the number of bits per sample is at least Rmin=_______, and the variance of the quantization error is _________V^2.

In vector quantization process, the input vector is matched with the codeword in the codebook with a kind of criterion named distortion measure.

For the ADC, when the word length increases by 1 bit, the SNR during quantization increases by about 6db.
