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

J. D. B. Lambert,K. K. Kadyrzhanovnvert the inputs into an analog output signal. (Often the “ones” are a reference voltage, . and the “zeros” are 0V.) 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.

https://doi.org/10.1007/978-1-4020-5903-2Before describing some of the converters that are available, we briefly consider the properties of the .—the op-amp. The op-amp is a building block in many of the circuits described in the following chapters.
