Microprocessor-Based Data Reduction and Compression Systems

Abstract

Data compression and reduction is used whenever a large amount of data values need to be stored and processed many times before transmission [1–18]. The advantages that are offered by data compression/reduction include: (i) storage saving (since less coefficients/points of smaller word length need to be stored for representing the waveform, (ii) computing time saving (since data reduction can take place simultaneously with data acquisition and processing requirements are reduced), (iii)data processing in real time (using the reduced/compressed data).
