Knud Kristensen,Elisabeth NørbygaardThe R-2R ladder DAC is another passive DAC. The R-2R ladder DAC makes use of only two resistor values—but it requires 2. resistors to implement an .-bit converter.

During and Post Pandemic PerspectivesWe now consider the single-slope and the dual-slope ADCs. Both ADCs make use of simple op-amp circuits and control logic to do most of their work. We explain why the slightly more complicated dual-slope ADC is generally a better choice of ADC than the single-slope converter.

Understanding SamplingIn Part I, we consider the analysis of discrete-time signals. In Chapter 1, we consider how discretizing a signal affects the signal’s Fourier transform. We derive the Nyquist sampling theorem, and we give conditions under which it is possible to reconstruct a continuous-time signal from its samples.

Signal ReconstructionWe have seen that if one samples a signal at more than twice the highest frequency contained in the signal, then it is possible, ., to reconstruct the signal. In this chapter, we consider the reconstruction problem from a somewhat more practical perspective.

Signal Generation with the Help of MATLABOne tool that an engineer often needs is a signal generator. Given a microprocessor with a stable time-base and a nice size block of FLASH memory, it is easy to build a simple signal generator. In this very practically oriented chapter, we show how.
