【摘要】：設(shè)計(jì)了一種用于聲光調(diào)制(AOM)通信系統(tǒng)的語(yǔ)音信號(hào)解調(diào)裝置,介紹了聲光調(diào)制的原理和語(yǔ)音信號(hào)解調(diào)裝置的電路結(jié)構(gòu),描述了基于聲光調(diào)制的語(yǔ)音傳輸系統(tǒng)的組成,基于該通信系統(tǒng)做了對(duì)于語(yǔ)音信號(hào)和TTL電平信號(hào)的傳輸解調(diào)實(shí)驗(yàn)并對(duì)結(jié)果進(jìn)行了分析。
[Abstract]:A kind of speech signal demodulation device used in acousto-optic modulation (AOM) communication system is designed. The principle of acousto-optic modulation and the circuit structure of speech signal demodulation device are introduced. The composition of voice transmission system based on acousto-optic modulation is described. Based on this communication system, the transmission and demodulation experiments of speech signal and TTL level signal are carried out and the results are analyzed.
