Signal Conditioning & PC-Based Data Acquisition Handbook


Chapter 2: Analogue-to-Digital Conversion
This chapter examines general considerations for analog-to-digital converter (ADC) measurements. Discussed are the four basic ADC types, providing a general description of each while comparing their speed and resolution. Issues such as calibration, linearity, missing codes, and noise are discussed, as are their effects on ADC accuracy.

This chapter also includes information on simultaneous sample and hold (SS&H) and selectable input ranges. Finally, this chapter contains a section on discrete sampling, which includes Fourier theory, aliasing, windowing, fast Fourier transforms (FFTs), standard Fourier transforms, and digital filtering.
