Generator of signalling tones for telephone exchange
Srnský, Petr ; Novotný, Vít (referee) ; Zeman, Václav (advisor)
The aim of this semestral thesis is the description and design of signal generator signals to the PBX using electronic components. The generator is used to generate a total of three rectangular signal harmonic signals and one sine wave signal, used for signaling in PABX. In the theoretical part are discussed and described the basic parameters of the alert signal and the ringing signal. In the practical part are designed individual blocks on signal generator. The generator is designed to lead in the panel permanently generated signals. The final section describes how the proposed generator function.

Fiber optic interferometry
Srnský, Petr ; Urban, František (referee) ; Čučka, Milan (advisor)
The aim of the diploma thesis is theoretical analysis of optical fiber sensory sensing using coherent and incoherent interferometry, creation of simulation models of interferometers and their practical measurement. The first part deals with the description of basic physical principles and interferometers. In the second part the thesis deals with the description and design of optical microphones, which are based on the principles of physical interferometers Michelson and Mach - Zehneder interferometer. Both models are simulated in the VPIphotonics simulation environment. In the third part of the thesis, both models are assembled and measured. The last part of the thesis presents the differences between the interferometers and the results of the measurements.

Fiber Optic Interferometry
Srnský, Petr
The aim of this thesis is a theoretical analysis of fiber sensoric sensing using coherent interferometry. The first part deals with the description of the sensoric fiber optic sensing and basic physical laws. In the second part is designed model of Mach-Zehnder interferometer in simulation environment VPI photonics. The latest proposal is focused on the implementation of Mach Zehnder interferometer for real functional connections.
