Texas Instruments’ switching noise on audio reduction using spread spectrum tech. Link here
Automotive systems have many regulations and requirements, from electromagnetic interference (EMI) to thermals to functional safety, but one consideration that stands above the rest when it comes to immediate consumer dissatisfaction is audible noise. In this technical article, I’ll discuss common sources of audible noise, and how devices with TI’s dual random spread spectrum (DRSS) technology can help you eliminate audible noise in your designs.
