Globalization and analog

摘要

The requirements of globalization often impact analog-system designers more than they do other designers because analog is the interface to the real world. That world changes from country to country and from culture to culture. The old phone system was one of the few systems that had some uniformity all over the world. In television, Europe has PAL (phase-alternation line), and the United States and Japan have NTSC (National Television System Committee). High-definition-TV standards remain unsettled, as content owners, such as the major studios, try to force hardware manufacturers to adopt DRM (digital-rights-management) schemes.
