Preface
It gives me immense pleasure to present my project that was done at RaneTRW, Power Steering Systems Ltd through this report. The project was conducted in a structured framework under the guidance of engineers working in the Gear Assembly section of (PR & P division).
The Gear Assembly section containing six assembly lines that have the capable of simultaneously assembling and testing gear components is at a distance of 70m (approx) from the HR division. Complaints and queries arising in the Assembly section require to be addressed to the HR division as soon as possible. In order to do that, a transmitter and receiver set up required to be created. This enables the transmission of complaints in the form of audio signals which is to be recorded at the reception end for later retrieval. The report gives a detailed description of the steps involved in choice of mode of transmission, creation of a transmitter and receiver set up and computer interfacing done at the HR division.
With this report, I intend to share the knowledge that I acquired during my project work. I have made a sincere attempt to make this report a simple, informative and useful one. I thank one and all for making this project a successful endeavor.

Aim of the project

To create a transmitter and receiver set up which enables transmission of a complaint in the form of an audio signal over a distance of 80 m. The signal obtained at the receiver
end must be interfaced with... [continues]
