November 16, 2009[Simply the Bits that Matter] Remove Redundancy In Your Compression Designs
All compression algorithms utilize two basic functions. The first removes redundant or irrelevant information. Redundancy removal can be lossless or lossy. The second function, bit packing, packs the redundancy remover’s outpt bits together in a lossless manner. Redundancy occurs when a signal stream contains more bits than required to represent the inherent information it carries. For instance, telephone calls could transmit the full 2-kHz bandwidth...

[Simply the Bits that Matter] Which Compression Format Provides The Most Bang For The Buck?
We all want value for our money, especially during the current economic downturn. But when it comes to compression algorithms, what’s the best way to determine value? Let’s take a look at audio compression algorithms and figure out which ones provide the best “bang for the buck.”
August 13, 2009[POV: Point Of View] Use Sampled Data Compression In Your ISM Applications
Compression is ubiquitous in consumer electronics. Modern compression algorithms exploit the limitations of human hearing and vision to offer compression ratios from 4:1 for speech and more than 30:1 for video, generating “good enough” audio and video for consumers. While these applications have used compression for years, many industrial, scientific, and medical (ISM) applications don’t use it. Many engineers in medical imaging, radar, sonar, test and...
