Despite the need for an IC, this ubiquitous interface between the modulator and audio-video signals has not been reduced to an integrated circuit. The major reasons for that deficiency are the ...

An in-line, all-optical fiber modulator based on a stereo graphene–microfiber structure (GMF) utilizing the lab-on-rod technique was demonstrated in this study. Owing to its unique spring-like ...

A sound amplification technique from SLS Loudspeakers (Springfield, MO) promises to reduce the size and cost of high-power, professional quality speakers. The approach, dubbed Evenstar, uses a pair of ...

Pulse Width Modulation (PWM) or Pulse Duration Modulation (PDM) is a technique of converting analog signals into rectangular waveforms. The width of the waveform varies in proportion with the ...

This work presents a novel laser-based optoacoustic transducer capable of reproducing controlled and continuous sound of arbitrary complexity in the air or on solid targets. Light-to-sound ...

New from Audemat at IBC2013 will be an updated version of the FM Modulation Analyzer. A new RF front end has been added to the unit and it is now available in two tailored and cost-effective packages.
