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 ...

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.

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 ...
