The demo shows the total harmonic distortion + noise (THD + N) ratio, a universal measure of sound quality for audio amplifiers. Featured White Papers Key Requirements for Multi-Tuner Automotive Radio Designs Automotive OEMs and Tier 1 suppliers understand that consumers expect a superior in-vehicle audio experience and are responding by designing sophisticated infotainment systems. The radio components used in today's vehicles need to be cost-effective while meeting rigorous automotive levels of performance. With the advent of multi-tuner automotive infotainment systems, car radio developers must now consider a wide range of performance requirements and new technologies in their designs. Designing Wheel-Tuned, Digital-Display Radios with Next-Generation Radio ICs As a growing number of portable applications such as mobile phones and portable media players integrate the FM radio function, there’s a misconception that traditional radios are no longer needed. In reality, wheel-tuned radios have remained immensely popular. This article will discuss how to design a mid-level wheel-tuned radio with an LCD to display frequencies, and it will explore the practical considerations in selecting audio ICs and display drivers, as well as how to leverage these technologies to deliver the best end-user radio tuning experience. Available in English and Simplified Chinese.
