With smart speakers being a relatively new class of consumer audio device with unique characteristics, testing the overall end-to-end performance of a smart speaker’s primary input and output audio paths can be quite challenging.
Smart speakers are a relatively new class of consumer audio device with unique characteristics that make testing/measuring their audio performance difficult. In this application note, we provide an overview of smart speaker acoustic measurements with a focus on frequency response - the most important objective measurement of a device’s audio quality.
This application note discusses the immunity of the RAA78815x family of RS-485/RS-422 transceivers to repetitive Electrical Fast Transients (EFT) as defined in IEC61000-4-4. It...
