  • Independent Component Analysis (ICA) is a signal-processing method to extract independent sources given only observed data that are mixtures of the unknown sources. Recently, Blind Source Separation (BSS) by ICA has received considerable attention because of its potential signal-processing applications such as speech enhancement systems, image processing, telecommunications, medical signal processing and several data mining issues.

  • What is a filter? A filter is a device that passes electric signals at certain frequencies or frequency ranges while preventing the passage of others. — Webster. Filter circuits are used in a wide variety of applications. In the field of telecommunication, band-pass filters are used in the audio frequency range (0 kHz to 20 kHz) for modems and speech processing. High-frequency band-pass filters (several hundred MHz) are used for channel selection in telephone central offices.

  • For years, television broadcasters have relied on coax cable to route video and audio control signals and RF around their facilities. Coax has proven itself to be easy to work with and reliable. However, as the television broadcast business evolves from a single analog channel to a digital world, the industry is re-evaluating the role of coax. In its place, fiber-optic cable is emerging as a logical solution for next-generation television signal routing, where greater bandwidth is needed to accommodate HD signals and multicast SD channels....
