Abstract

This invention relates to a high tone quality device provided by a intermediate value filter in acoustic system. It contains a receiving circuit receiving a RF signal and generating a BF signal, a signal demodulation module for demodulating the said BF signal and outputting continuous data sample points in sequence, in which, each point has a sample value, a time pulse group control unit (BMC) providing time sequence control to the sample points and data synchron. A intermediate value filter for removing mistaken data output by the said BMC and a phonetic converting device converting the data output by the filter to sound signal.

Description

technical field [0001] The present invention provides a device used in an audio system to improve output sound quality, in particular to a device used in a wireless audio system that uses a median filter to filter out stray signals and reduce popping sounds. Background technique [0002] Sound has always been one of the most basic and intuitive ways for human beings to communicate. All voices for exchanging information and pleasant music are transmitted through sound. Even today with advanced technology, audio information has never lost its importance. The audio system used to play sound is the focus of research and development in the information industry today. Especially with the development of radio technology in recent years, wireless audio systems can transfer sound signals to radio for transmission, and then convert them into sound signals for playback. Generally speaking, the signal is easily interfered by stray signals during the wireless transmission process, so i...
