Understanding how these conversions are made is the purpose of this part of the book—of Part

In this chapter, we present one simple, albeit not very practical, DAC. This DAC can be used with many types of microprocessors and can be considered a purely passive DAC.

The Oversight of Planned Release in the UKIn 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.

Non-Probabilistic Factor of Safety,One 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.
