DESIGN AND CONSTRUCTION OF POWER AND AUDIO AMPLIFIER
of this project
is ” Audio Amplifier”. The research
embarked upon this study or project by using both primary and secondary source of data.
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.
