Audio Amplifier Design and Construction

Description

The auditory system of a person requires high quality sound that covers a wide band of frequencies. The natural response of such a sensory system ensures that a person achieves complete and undistorted sound information for easier manipulation and interpretation. This human desire can be achieved through professionally designed audio amplifiers, which generates an amplified high-fidelity audio with standard qualities acceptable by the auditory system. Unprofessional audio amplifiers, which often contain imperfect filters, may unnecessarily magnify noise present in the input signal and cause undesirable disturbances to the listener. This training gives fundamental practical principles to design and implement professional amplifiers. Participants will learn building blocks of high-fidelity (Hi-Fi) audio amplifiers, and design corresponding electronic circuits to amplify small signals. In addition, concepts of sound acquisition, processing, storage, and transmission will be discussed in detail. The training is hands-on, and participants will practically learn how to design their own Hi-Fi audio amplifiers depending upon the specifications given by the clients.

Objectives

To equip participants with professional skills in designing and constructing audio amplifiers.
