Abstract

The aim of bachelor thesis about the design of the amplifiers changing the dynamics of the signal, was to clarify the use of these amplifiers in the various fields of electronics and the subsequent design of the amplifier. It is divided into two main parts. Theoretical and practical. The theoretical part contains four chapters dealing with the introduction, the history, principles of operations, properties and parameters and use such circuits in the amplifier electronics. The practical part consists of the possibility of implementing circuits using AVC with high-frequency amplifier, compressor and expander implementation using analog circuits and the last chapter is devoted to design of compressor / limiter. The circuit is implemented using inverting operational amplifier connected as an operational transducer and its output characteristics is measured. In this work, emphasis is on the clarification of concepts and parameters related to the amplifier.
