Abstract

Uniformly sampling with an analog to digital (A/D) converter can lead to the phenomenon known as aliasing. Aliasing occurs when more than one frequency fits the sampled data points. These frequencies Include the true frequency plus the aliases. Obtaining data with a random time step can reduce this problem. When a signal Is sampled with a random time step, only the true frequency will fit all of the sampled data points. This project uses two random time sampling methods to demonstrate the utility of random time sampling. Both methods produce the expected results.
