Digital signal processing is generally applied to various kinds of modern technology, from audio and image processing to telecommunications and data analysis.
Traditional digital signal processing systems are highly concentrated and coordinated and operate under the common assumption that the sampling rates are perfect and consistent. In many real-world data processing applications, this idealized scenario is unrealistic because of messy and/or out-of-order data. This requires a different approach to bridge the gap between ideal sampling and real-world data streams.
