Abstract:
The objective of this research is to design audio and video transmitter and receiver. The motive is to provide a fast and secure communication between transmitter and a receiver. The medium of communication is laser. The laser carries audio and video and is received with the help phototransistor. LM386 audio amplifier IC is used to filter the audio signal and an error free audio is available. The video is received and an LCD is used to show video. To minimize cost laser was used to transmit signals via line of sight instead of fiber optic. This project is cost effective while achieving the goals and an estimate of the cost is also made.
