Design And Construction Of An Audio Amplifier

Project and Seminar Material For Electrical Electronics Engineering EEE

Design And Construction Of An Audio Amplifier


The topic of this project is ” Audio Amplifier”. The research embarked upon this study or project by using both primary and secondary source of data.

The main instrument used for data collection are:

  • Modern electronics circuit Design. By David J. Commer.
  • Electronics Devices. By Floyd
  • Electrical Installation Theory and Practice. By Dennelly E.L.
  • Electronics IV. By Dr. Green
  • Electronics II. By Ejinofor C.O.
  • Radio and Transmission “A”. BY D.C. Green
  • Electronics e Fault Diagnosis. By Loveday.

The research discovered that this fays people normally have to address large gatherings data time and an efficient means of communication has to be used, if not, the message can not be heard by people at long range.
The researcher recommended that use of amplifier should be made effective so that people can address large gathering at a time so that were ever you are you will be communicated.
