TECH TRENDS: Front-end voice activation improves auto safety Design How-To 10/20/2011 7 comments The real problem for drivers is distractions, and the desire for additional productivity or entertainment that creates them. Distractions can be reduced through voice user interfaces to control the car without looking at buttons, and without having to touch them. Front-end voice activation is the next step in improving user interfaces.
A measurement approach for IQ offset and imbalance of LTE mobile devices Design How-To 10/13/2011 Post a comment Imperfect analog front-ends of mobile devices cause transmit signals to be non-ideal. Typically, the signal processing for inphase and quadrature (IQ) components is likewise affected. On the one hand, the undesirable zero-offsets of both digital-to-analog converters lead to the IQ offset, and on the other hand, the IQ imbalance originates from an imperfect up-conversion of the baseband signal.
Options for simulating wideband signals Design How-To 10/11/2011 Post a comment The need to take baseband signals and modulate them onto higher frequency carriers is fundamental for both the design and evaluation of communication and radar systems. How do we go about modulating and then upconverting wideband signals to their operational carrier frequencies for simulation?
E.T. phone home? Blog 10/5/2011 2 comments It’s said that for any sufficiently complex product, 80 percent of the users use only 20 percent of its features. I’d be willing to wager that’s true for Keithley Instruments’ products and plenty of other test and measurement instruments as well. Only problem is, how can I collect on that bet?
In conjunction with unveiling of EE Times’ Silicon 60 list, journalist & Silicon 60 researcher Peter Clarke hosts a conversation on startups in the electronics industry. One of Silicon Valley's great contributions to the world has been the demonstration of how the application of entrepreneurship and venture capital to electronics and semiconductor hardware can create wealth with developments in semiconductors, displays, design automation, MEMS and across the breadth of hardware developments. But in recent years concerns have been raised that traditional venture capital has turned its back on hardware-related startups in favor of software and Internet applications and services. Panelists from incubators join Peter Clarke in debate.
