WebAudio bit depth. An analog signal (in red) encoded to 4-bit PCM digital samples (in blue); the bit depth is four, so each sample's amplitude is one of 16 possible values. In digital audio using pulse-code modulation (PCM), bit depth is the number of bits of information in each sample, and it directly corresponds to the resolution of each sample. WebThe DAC sampling capacitance is only 1pF from b15-b12 and b12r, which greatly eases the input driver and reference buffer requirements. Three redundant capacitors (b12r, b8r, b4r) are included to tolerate decision errors [22], [23] from the flash sub-ADC and earlier bit trials.
