ABSTRACT

This thesis guides the account for the design and construction of a 100w audio power amplifier with the objective of producing a reliable and cheaper amplifier that can be used in a household or stage. The audio power amplifier was constructed with electrical/electronic components such as resistors, capacitors, transformer, transistors and vice-versa. Many tools/instruments like soldering iron, multi-meter and so on were used. The 100w audio power amplifier when compared with other types of audio power amplifier of the same rating in the market is cheaper as the components and materials used ere locally sourced and selected to suit the desired purpose and environment.


Design and Construction of 100watt Audio Power Amplifier

CHAPTER ONE

1.1 Introduction

This is an exceptionally well designed amplifier, with a lot of power reserved in it. It has a high sensitivity, low consumption and full protection. Having all these ideal characteristics, this amplifier is likely to become the basic building block of the future high fidelity system or it may also become the element that will help improve or upgrade existing system.

The construction of a 100watts audio amplifier is a very big challenge and task to the group. As a matter of fact, an audio amplifier is one of the most important electronic devices which is commonly used around us. i.e in our say day activity either for domestic of commercial purposes. It should be able to deliver a high performance up to 40watts of continuous average power to an 8 load with 0.1% THD+N from 20Hz with excellent signal to noise ratio of greater than 95 bB(min) with a typical low noise floor of 2.0uv.

The study of this project has been carefully and thoroughly organized for easy understanding for whoever may be interested in reading the report.

Defense Procedure for Electrical / Electronics Engineering Researchers

In preparation for defending a project or seminar on Design and Construction of 100watt Audio Power Amplifier, it is imperative that as a nursing student, you demonstrate comprehensive knowledge of your research. The defense process is structured to include presenting your work, answering questions, and illustrating its pertinence. Initially, provide a succinct yet thorough introduction to your research topic, emphasizing its importance and the objectives, ensuring that both the audience and the External Examiner can understand the scope of your study.

Prior to your defense, be thoroughly acquainted with your research abstract and the critical elements of Chapter One, including motivation for embarking on this research, problem statement, objectives, and significance. In Chapter Two, be ready to cite at least two references from the literature review. For Chapter Three, you should be equipped to discuss the methodologies, tools, and techniques utilized. In Chapter Four, defend your research by justifying the findings and linking them to your research objectives.

Conclude your defense by succinctly summarizing the study and offering insightful, evidence-based recommendations. A professional dress code, such as wearing a suit and tie, is vital to create a favorable impression and elevate your presentation.

During the question and answer segment, the External Examiner may pose questions pertaining to your research. If confronted with a challenging or irrelevant question, respond diplomatically with, “Sorry, Sir/Madam, the question asked is beyond the scope of my study.” Whenever possible, direct your answers back to your research findings to reinforce your expertise.
