Apple set for 50% margins on iPhone, says iSuppli Design How-To 1/18/2007 Post a comment The cost of manufacturing each 4GB version Apple's iPhone is put by market analyst group iSuppli at about $230, meaning each of the phones sold could generate a 50.7 percent gross margin for Apple Inc. and partner Cingular Wireless.
Design of High-Performance Balanced Audio Interfaces - Part 6 Design How-To 1/14/2007 Post a comment Balanced inputs benefit from specialized circuitry. The InGenius circuit silicon implementation differs from the discrete solution in many respects. Since all critical components are integrated, a well controlled interaction between resistor values and metal traces can be duplicated with similar performance from die to die. But the integration of certain components creates new challenges.

Design of High-Performance Balanced Audio Interfaces - Part 4 Design How-To 1/10/2007 Post a comment High signal-to-noise ratio is an important goal for most audio systems. However, ac power connections unavoidably create ground voltage differences, magnetic fields, and electric fields. Balanced interfaces, in theory, are totally immune to such interference. Bill Whitlock describes a new type of IC used to create balanced interfaces.
