Optical vector analysis has emerged as a critical tool for characterising optical devices, enabling simultaneous measurement of amplitude and phase responses over wide bandwidths. This technique is ...

The advent of all‐optical modulation format conversion techniques has fundamentally reshaped modern optical communications. These techniques enable the direct manipulation of optical signals in their ...

Fundamental to all wireless communications is modulation, the process of impressing the data to be transmitted on the radio carrier. Most wireless transmissions today are digital, and with the limited ...

Abstract: High-phase-count machines are well known to have reduced dc bus utilization compared to conventional three-phase drives. High-phase-count machines for fault tolerance and variable-pole ...

Abstract: Four types of carrier-based pulse width modulation (CBPWM) techniques used to control a two-cell single-phase cascaded H-bridge (CHB) inverter with separated dc power sources, are compared ...

Power-density improvements are an increasingly elusive goal as designers exhaust the easiest or most obvious solutions. One direction that’s now being explored more thoroughly is advanced modulation ...
