3Source Coding/Data CompressionMany digital data streams contain much redundant information. A digital picture file might contain many more 0’s than 1’s: 0 0 0 0 0 0 0 1 0 0 0 1 0 0 0 0 1The operation of eliminating redundant data is called source coding or data compression.Unlike quantization, source coding can compress data without introducing distortion.Source coding is particularly important when bandwidth is expensive (e.g. FAX machines).Source coding is also important for storage of information on magnetic or optical media.
