[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.
