A new holographic technique that achieves dynamic high-contrast imaging offers a unique solution for studying biological processes at the molecular level. A team of US, Swiss and German scientists has ...

The need for improvements in terahertz-spectrum sources. How lasers and graphene layers are being used to create harmonics into the THz band. The multiple experiments that were run and the overview of ...

November 18, 2012. Rohde & Schwarz announced it now offers harmonic filter options for its R&S SMB100A microwave signal generator. These filters make it possible to achieve a harmonic suppression of ...

Scientists have found a way to see ultrafast molecular interactions inside liquids using an extreme laser technique once thought impossible for fluids. When they mixed nearly identical chemicals, one ...

Mixed-signal printed circuit boards (PCBs) present unique challenges in high-performance applications, such as vibration analysis and other multi-channel data acquisition systems. Nonlinear ...

When discussing electronic circuits, I often lock onto the circuit's magnitude characteristics. For example, we refer to filters as high pass, low pass, or band pass, which is a shorthand way to ...
