Methods of acoustic signal sources impedance matching for their further processing
Havelková, Nikola ; Kubánek, David (referee) ; Koton, Jaroslav (advisor)
The purpose of this bachelor thesis is to get acquainted with the theoretical areas related to the issue of impedance matching using the so-called DI boxes. It is mainly the theory of balanced and unbalanced signal, parameters typical for DI boxes (THD, impedance, bandwidth, dynamic range, etc.), knowledge about the transformer, respectively about the coils, or last but not least the issue of operational amplifiers, which is for designing of active DI box absolutely essential. The specifications of the designed DI box based on this theory are subsequently determined and compared with commercially available models. The main target is to achieve better figures or at least get closer to them. Furthermore, the circuit diagram is designed and optimized to achieve predetermined parameters using simulation in the Multisim program from National Instruments. Regarding the resulting specifications of the DI box, a printed circuit board is designed to build a prototype of the device. After its completion, a test gauging using APx525 is done and the results are compared to the target figures.
