Abstract

The invention discloses a signal high-fidelity wireless audio receiving system based on phase processing. The system is characterized in that the system is mainly composed of a processing chip U, a capacitor C12 of which the positive electrode is connected with the -IN pin of the processing chip U through a resistor R12 and the negative electrode is connected with the GND pin of the processing chip U and grounded, and a capacitor C13 of which the positive electrode is connected with the OUT pin of the processing chip U and the negative electrode acts as the output end. The interference signals doped in audio signals in the wireless transmission process can be filtered at the receiving end and the output end, and the interference signals can be filtered by using the mode of double filtering so that the filtering effect is enabled to be more thorough, the outputted audio signals are enabled to be cleaner, the playing quality of sound can be enhanced and the people's auditory effect is enabled to be better.

Description

technical field [0001] The invention relates to the field of wireless transmission, in particular to a signal high-fidelity wireless audio receiving system based on phase processing. Background technique [0002] The wireless audio signal transmission system consists of a wireless transmitting system and a wireless receiving system. It is used for long-distance wireless transmission of audio signals. It has been widely used in people's lives and has brought great convenience to people's lives. With the continuous improvement of people's living standards, people's requirements for sound quality are also getting higher and higher. However, when the wireless audio signal transmission system wirelessly transmits the audio signal, there are usually interference signals doped into the audio signal. Due to the influence of the interference signal, there will be a lot of noise in the sound output at the receiving end. Seriously affect people's hearing effect. Therefore, it is an u...
