Design and realization of D class audio amplifier controlled by microcontroller
Dobesch, Aleš ; Frýza, Tomáš (referee) ; Adamec, Filip (advisor)
The aim of the bachelor’s thesis is to design and construct D Class power amplifier of small proportions using modern integrated circuits. Implement a control software and measure parameters. Thesis describes principle of D Class power amplifiers, choosing suitable components and complete hardware device solution. Control unit is provided by microcontroller AVR ATmega164PA. This power amplifier is extended with radio remote control and effective box.
IR thermometer with automatic emissivity correction
Dobesch, Aleš ; Tannenberg, Milan (referee) ; Poliak, Juraj (advisor)
Diploma thesis deals with basic physical quantities and laws relating to non-contact temperature measurement and emissivity determination of solids. It describes the design and implementation of the IR (Infra-Red) thermometer often missed with automatic emissivity correction. The first chapter explains the concept of temperature and basic principles of temperature measuring . The second chapter focuses on the history and theory of non-contact temperature measurement. Gradually are explained the concepts related to non-contact temperature measurement and the problem of determining the emissivity of the body. Next third chapter describes the proposed hardware solution of IR thermometer. The fourth chapter describes a software written for the IR thermometer. The fifth and last chapter summarizes the findings and knowledge from the implementation of non-contact thermometer and measuring emissivity.
