The purpose of this paper is to show the importance of using both time and frequency-domain analysis when working with sampled data. To make things interesting we sample a sine wave(s) close to the Nyquist frequency. Sampling or the discretization of time is what makes DSP unique as compared to pure analog signal processing. In this paper we investigate the beat effect introduced by sampling and compare it with the conventional beat frequency effect you may have experienced when working with two tone audio signals. It turns out that you can introduce a beating effect when sampling even a single sine tone.

Made a few small changes to the language in the description and the associated white paper in the attached zip file. The models are unchanged.
1.1.0.0

updated the PDF description of the models and broke out the examples into separate SLX files instead of combining them into one.
