Research and Implementation of Airborne Digital Audio Technology

The communication and navigation audio for civil aircraft has transitioned from analog to digital, offering features such as anti-interference and ease of signal processing. This article examines airborne digital audio technology and introduces a low-cost method for low-delay airborne digital audio based on the bandwidth characteristics of common airborne radio. This method can provide practical insights into narrowband audio segments and lay the groundwork for the future digitization of wideband audio communication systems.
