A kind of general audio frequency periodic noise suppressor
一種通用的音頻周期性噪聲抑制器The precise clock source is crystal oscillator made of 74hc04 ; the mute circuit can conceal the error and solve the problem of noise ; the antenna switching circuit in the receiver is to select one antenna from two which receives signal better. it can improve the quality of the receiving audio signal, restrain the noise effectively and promote the system performance
高精度的時鐘源是由74hc04構成的晶體振蕩器;靜音電路將出錯的音頻信號進行差錯掩蓋,很好地解決了噪聲問題;接收機採用兩副天線切換工作,提高了音頻信號接收質量,有效地抑制干擾,提升了系統的性能。The research content of the thesis is the speech enhancement technique that is used in the acoustic feedback suppresser. firstly, we searched and compared the methods of noise estimation based on vad and updating the noise spectrum continuously, combined them together to make some improvement. secondly, we research on some speech enhance techniques including short time spectrum analysis speech enhance technique and its improvement form, simulated the algorithms and compared them each other
