Abstract

This bachelor thesis focuses on a deeper knowledge in the area of audio amplifiers and realization of laboratory tool with measurable amplifier modules. The theoretical part explains the basic principles amplifiers, sort by the applicable active element, working classes and their properties by harmonic distortion and efficiency. The practical part is focused on the design and realization of different classes modules of amplifiers, which are measurable in the laboratory. Measuring tool is designed to exchanging individual amplifier modules plugging into the socket, with power supply and measuring terminals. Additional modules must be creating with right dimensions PCB. Instruction manual and measurement procedure is on attached CD.
