Teledyne LeCroy DesignCon 2012 - The Relationship Between Discrete-Frequency S-parameters and Continuous-Frequency Responses

White Paper
S-Parameters
Continuous Frequency Responses

We explore in detail the relationship between discrete-frequency responses connected with sparameters and the implied continuous time response. This is done in both the frequency- and time-domain to develop the proper insight and explore issues with real time-domain responses, time-aliasing, causality, interpolation and re-sampling of discrete-frequency data. Using the insight gained, we identify the conditions for sufficiency of sampling and the side-effects of the invariable practical conditions when these side-effects cannot be completely dispelled. This paper is especially useful for understanding issues involved in direct application of sparameters in linear simulations, like those used in virtual probing applications in scopes.
