Effects of Aperture Time and Jitter in a Sampled Data System

چکیده
© 1994 National Semiconductor Corporation http://www.national.com Printed in the U.S.A. The Nyquist sampling theorem states that band limited signals may be represented without error by sampled data. Among the effects which place additional restrictions on the signal, beyond those which are given by the Nyquist theorem, are aperture effects. Aperture effects such as aperture jitter, and aperture time, contribute to a signal degradation which is frequency dependent. In applications for high performance A/D converters, the aperture effects may be the dominant source of noise in the digitization process.

AD-03 Effects of Aperture Time and Jitter in a Sampled Data
The Nyquist sampling theorem states that band limited signals may be represented without error by sampled data. Among the effects which place additional restrictions on the signal, beyond those which are given by the Nyquist theorem, are aperture effects. Aperture effects such as aperture jitter, and aperture time, contribute to a signal degradation which is frequency dependent. In applications...
متن کاملAperture Jitter Effects in Software Radio GNSS Receivers
Increasingly, software radio techniques are being used in the implementation of communications receivers in general, and GNSS receivers in particular. In such a receiver, the received signal is sampled as close to the receive antenna as possible, and all subsequent processing uses digital signal processing (DSP) techniques. The sampling clock will suffer from phase noise instabilities, leading ...
متن کاملModeling of Jitter Characteristics for the Second Order Bang-Bang CDR
Bang-Bang clock and data recovery (BBCDR) circuits are hard nonlinear systems due to the nonlinearity introduced by the binary phase detector (BPD). The specification of the CDR frequency response is determined by jitter tolerance and jitter transfer. In this paper, jitter transfer and jitter tolerance of the second-order BBCDR are characterized by formulating the time domain waveforms. As a re...
متن کاملAN-501 Appl Note
Aperture Uncertainty One of the key concerns when performing IF sampling is that of aperture jitter or aperture uncertainty. The terms aperture jitter and aperture uncertainty are frequently interchanged in text. In this application, they have the same meaning. Aperture uncertainty is the sample-tosample variation in the encode process. Aperture uncertainty has three residual effects: the first...
متن کاملStructural Properties of Multirate Sampled-Data Systems
The application of Networked Control Systems (NCS) in which sensory and control signals are transmitted via shared data communication networks, is growing significantly and these systems have been the subject of research during the last decade. On the other hand, multirate sampled data systems have been investigated since a long time. In this paper, conditions under which a networked control sy...
