提出了一种利用激光技术传输音频信号的替代方法。本文主要研究音频放大器子系统的设计、仿真和性能结果。利用PSPICE计算机仿真软件对音频放大器子系统的理论设计进行了研究。在噪声输入级、高电压增益单元和低阻抗驱动器三个连接点对音频放大器进行了测试。通过理论计算、PSPICE计算机软件仿真、示波器测试成品等设计过程，对音频放大器进行了深入研究和验证，以达到预期的功能。此外，还对脉冲宽度调制技术进行了研究和实现，并用精密555定时器实现了通过激光传输音频信号。

An alternative method for transmittingaudio signals via the use of laser technology was presented here. The primaryfocus of this document is on the audio amplifier subsystem including thedesign, simulation, and performance results. Simulations using the PSPICEcomputer simulation software were utilized to investigate the theoreticaldesigns of the audio amplifier subsystem. The audio amplifier was examined inthree junctures including the noisecanceling input stage, the high voltage gaincell, and the low impedance driver. Through the design procedure usingtheoretical calculations, simulations using PSPICE computer software, and examinationof the finished product with an oscilloscope, the audio amplifier was greatlyinvestigated and verified for desired functionality. In addition, thepulse-width modulation technique was examined and implemented with precision555 timers in order to transmit audio signals via laser.
