Section 1.05.6, covers the principles of quantization, both in ADCs and internally in digital systems, as they are closely related. In Section 1.05.7, oversampled ADCs and DACs are briefly discussed. Oversamplin
Quantization noiseTime-interleaved samplingCompressed sensingA digital signal acquisition system consists of two steps: sampling and quantization. Sampling maps a continuous signal to a digital signal, which then is quantized into a finite number of bits. Generally, a high sampling rate can ensure ...
The two most important characteristics to look for in the selection of ADC are sampling rate and resolution; from the cost to the architecture of the ADC, sampling rate and resolution play an important role. Resolution Resolution refers to the number of quantization bits of the ADC. It is the...

This is approximated by a sawtooth signal, as it is considered that an uncorrelated sawtooth waveform is a good representation of the quantization error for any AC signal, and that it behaves like wideband noise. Figure 1. Ideal N-bit ADC quantizatio...
