The present study investigates the effects of irregular data distribution on the corresponding frequency representation. For a basic understanding it starts with a simple ID-model and provides a description of effects emerging from transition of the infinite continuous to the finite discrete case. Considering regular (gridded) and irregular data distributions and even gap regions without data coverage, the corresponding results in frequency domain and the numerical stability are analyzed using trigonometric functions as base functions.
