Digital signal processing is generally applied to various kinds of modern technology, from audio and image processing to telecommunications and data analysis.

Digital Signal Processing with Real-World Data

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.
