the digital signal.
The analog signal does not exhibit continuity due to the quantization distortions, 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 when audio signals are played back.
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 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 0.056 x 10exp-6. This quantization error expresses itself during the playback of audio signals by noise, the quantization noise.
