Peak Signal-To-Noise Ratio As An Image Quality Metric


The term peak signal-to-noise ratio (PSNR) is an expression for the ratio between the maximum possible value (power) of a signal and the power of distorting noise that affects the quality of its representation. Because many signals have a very wide dynamic range, (ratio between the largest and smallest possible values of a changeable quantity) the PSNR is usually expressed in terms of the logar... » read more

Deals Dialog Semiconductor made a blockbuster deal with Apple – the chip company will license power management technologies and transfer some assets to Apple, which will use them in their internal chip research and development. More than 300 Dialog employees, mostly engineers, will join Apple, which will pay $300 million in cash for the transaction and prepay another $300 million for Dialog ... » read more

Lab-To-Fab Testing


Test equipment vendors are working on integrating testing and simulation in the lab with testing done later in the fab, setting the stage for what potentially could be the most significant change in semiconductor test in years. If they are successful, this could greatly simplify design for test, which has become increasingly difficult as chips get more complex, denser, and as more heterogene... » read more

Test and packaging In a major surprise, Cohu has entered into a definitive agreement to acquire Xcerra for approximately $796 million. With the deal, Cohu will enter the ATE market. Last year, a group from China entered into a definitive agreement under which it would acquire Xcerra. But the U.S. blocked Xcerra’s sale to the Chinese group. Ironically, at one time, Cohu was reportedly lobbyin... » read more

Details on the agenda and the full four-day program are available here. I’ve attended NIWeek for the past two years, and it’s an opportunity to learn new things, see impressive product demonstrations, and hear about developments ... » read more

Wireless Test Faces New Challenges


Your mobile phone is far more complex than it was even five years ago, and it’s about to become even more complex with new wireless technologies. That has set off a scramble among test equipment vendors to come up with solutions, methodologies and equipment that is affordable, effective and reliable enough to make sure all of this technology works as planned—and that it continues to work th... » read more
