Editor’s Note: This is a four-part series of DIs proposing improvements in the performance of a “traditional” PWM—one whose output is a duty cycle-variable rectangular pulse which requires filtering ...

The transfer function presented in part 1 is highly effective for designing a wide variety of filters. However, as with many numerical techniques, there are those cases where this function will return ...

People have asked for more information about analog and digital filters, so I'll devote a few columns to those topics. As taught to students in engineering schools, filters can seem like a math jungle ...

Cuing covert spatial attention can increase spatial resolution. Here we pinpointed the specific locus of this effect using texture segmentation. At the level of visual cortex, texture segmentation ...
