WebSep 1, 2016 · A novel dithering-based calibration technique to correct capacitor mismatch in digital-to-analogue converter (DAC) used in successive approximation register analogue-to-digital converters is proposed. With dithering, weights of most significant bit capacitors can be measured accurately, which relaxes matching requirement in capacitive DAC. 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. howarth timber supplies rochdale
