Due to the quantization distortions, the analog signal does not exhibit any continuity, but is more or less staircase-shaped depending on the number of bits.
The higher the quantization, the lower the quantization error, which is noticeable as quantization noise in the playback of audio signals. With 4-bit quantization, the dynamic range is 24.08 dB and the maximum quantization error is 6.25%. With 8-bit the dynamic range is 48.16 dB and the max. quantization error is 0.39 %, with 16-bit it is 96.3 dB and 0.015 % and with 24-bit the max. dynamic range is 144.5 dB and the possible quantization error is '0.056*10°-6'. This quantization error is expressed by noise during the playback of audio signals, the quantization noise.
