Non-uniform Sampling

Non-uniform sampling is a technique where data points are collected at irregular time intervals rather than at constant, regular intervals. This approach allows for more flexible data collection, focusing on periods when rapid changes or important events occur, while sampling less frequently during stable periods. It can improve efficiency, reduce data storage, and sometimes enhance the accuracy of analyzing signals or systems, especially when the phenomena being measured vary unpredictably or have specific moments of interest. Essentially, it’s about sampling smarter, not just more uniformly.
