Abstract: A novel absorption band-pass filter (ABF) with wide relative bandwidth and compact structure is proposed and investigated. The ABF consists of two identical 3dB directional coupler (DTC) and ...

Editor’s Note: In this article Peter Sarson and Andreas Wild of ams explain a new method to address the ridiculous amount of stress added to the testing process when RF filter characterization ...

Abstract: Capitalizing two silicon rings assisted a Mach-Zehnder interferometer (MZI) structure, we propose and demonstrate picometer narrowband optical filters featuring widely tunable bandwidths, ...

All of today's high-speed real-time sampling oscilloscopes use various forms of digital signal processing (DSP) on digitized oscilloscope waveforms. Some engineers are concerned that filtering ...
