DESIGN AND CONSTRUCTION OF A WIRELESS PUBLIC ADDRESS SYSTEM

Abstract

The principle behind public system and a wireless microphone is assessed in this write up. The Audio amplifier performs an essential role in communication process, in view of this it becomes imperative that the behaviour of transistors and integrated circuits have been studied, analyzed in terms of their characteristic functionality. In the design and construction of the audio amplifier and wireless microphones, the receiver and other devices such as the ICs and capacitor become veritable components. Graphical simulations, sketches and mathematical expressions are provided where necessary for the purpose of clarity, objectivity and understanding. Also, Computer Aided simulations have been carried out on the design to verify the correctness and proper functioning of the system design. This write up cannot present an exhaustive analysis of transistors rather, the aim is to give a basic understanding of how such a device in addition to transistors; capacitors operate and to illustrate some ways in which they are designed and constructed
