Quantisierung analoger Signale
1996Quantisierung [quantization] analoger Signale als Trager von Informationen ist die Grundlage fur ihre diskrete Ubertragung und Verarbeitung. Da sehr oft Informationen von kontinuierlichen Quellen erzeugt werden (wie z. B. die Messung physikalischer Grosen, das Sprechen von Personen), deren Verarbeitung und Ubertragung in informationstechnischen ...

In this chapter, we go beyond the time series analyses we explored in the last two chapters and introduce signal processing in the frequency domain. To get to the frequency domain, we use the Fourier transform. In the process, we aim to demystify the Fourier transform and discuss the merits of a frequency space representation of periodic signals.

Abstract This chapter sheds light on the challenges involved in diagnosing faults in analog, mixed-signal, and RF circuits. It describes some of the work being done to leverage the benefits of standardization, improve fault simulation tools, and overcome limitations on optical fault isolation techniques.

This chapter will describe a wide range of signal types that can be generated by the periodic bitstream approach, e.g., DC and AC signals, and various digital communication-type pulses. In addition, this chapter will also address silicon implementation requirements.

This chapter presents an overview of the analog and digital signals. A digital or binary, signal can have only two possible specified levels or states:—an “on” state, in which the signal is at its highest level and an “off” state, in which the signal is at its lowest level. Analog signals contain information within the variation in the magnitude of the

As the theory of Digital Signal Processing (DSP) is based on its predecessor, Analog Signal Processing (ASP), a study of analog signals and systems is necessary. This chapter handles the representation of analog signals and systems in the time domain and in the frequency domain.

The optical coupling of analog signals
1995 IEEE Nuclear Science Symposium and Medical Imaging Conference Record, 1996An opto-coupling circuit based on the Siemens IL300 linear optocoupler and the methods to assess its static and dynamic performances are presented. It is shown that IL300, due to its built-in linearizing feedback photodiode, makes it possible to build coupling schemes that associate good linearity with the inherent properties of optical devices, as ...

“Digital” has been the buzz word for the last couple of decades. The latest and greatest electronic devices have been marketed as digital and cardiology equipment has been no exception. “Analog” has the connotation of being old and outdated, while “digital” has been associated with new and advanced.

Analog signal metrology for mixed signal ICs
Proceedings Sixth Asian Test Symposium (ATS'97), 1999Signal reconstruction reconstructs a multiple period low-rate sampled waveform into a one-period high-rate sampled waveform. With which, we are able to provide sufficient samples of analog signals for DSP based testing using on-chip ADCs. Test results show that a 128-sample-per-period waveform can be reconstructed from a 2.4 samples per period waveform
