摘要
音频光纤传输系统传输高保真双声道音频信号,系统由编码及解码两部分组成,叙述了系统设计方案及电路工作原理以及测试结果。此系统电路功耗低,价格便宜,实现了低失真、频响平坦的音频传输。
The proposed system can transmit Hi-Fi stereo audio through fibre-optical. The system is composed of eneoder and decoder. The sampling frequency is 192 kHz and quantification is 24 bit. The whole transmition system has achieved the professional audio level. This system circuit is inexpensive, and the power consumption is low. The distortion adds the noise in less than 0.01%. From 20 Hz to 20 kHz, frequency response unbalancedness is less than 0.2 dB.
