摘要：

In this work, a Wien Bridge Oscillator and a Triangle Wave Oscillator were used to obtain a 40 KHz sine wave and a 400 KHz triangular wave respectively. A modified pulse using a comparator circuit was obtained to control the laser transmission circuit and to send the modified laser pulse to the photodiode receiving circuit in any distance. The original sine wave (40 KHz) was then retrieved to be used in medical, industrial, physical and military applications.
