Levels, peaks, slopes... which sampling for which purpose?

Level and peak sampling on a small ECG fragment


There are many ways to nonuniformly sample a signal, the most widely used, but not only, way to perform it being level crossing. The targeted application, and also the characteristics of the signal, can lead to various choices of samplings, to ensure a good representation of the input signal or robustness with respect to noise.
