Analysis of frequency and transient properties of non-integer order filters
Cieslar, Šimon ; Kubánek, David (referee) ; Koton, Jaroslav (advisor)
The bachelor thesis deals with analysis of frequency and transient properties of noninteger ( + )-order filters. These filters allow the use of a lower order, compared to the next higher integer-order ( + 1). For example, a system should be created, but a second order would not be sufficient, and in case of the integer-order, a third order system would be considered, but in the case of using a non-integer-order, a fractal-order between them can be used. In the following documentation, attention is paid to the defined group of fractal-order transfer functions, which approximate the identical course of the modulus characteristic according to Butterworth. The form of the function of the linear systems was not taken into account and characteristics such as phase response, group delay, step response and stability were analyzed and evaluated. All for the system ( + )-order, where 3, 4, variable Z1, 4 for (3 + )-order, variable Z1, 5 for (4 + )-order, and (0, 1). Non-integer systems offer a infinite number of orders, making them sometimes more advantageous in a step response or group delay. They can also provide an additional degree of freedom in designing a filter to fine-tune the slope of the amplitude characteristic in the bandwidth. The bachelor thesis deals with non-integer orders and their use in the case of required properties. For easier selection of the correct non-integer order with respect to the required properties, a design recommendation was written within the bachelor’s thesis.

Selective Circuits - Laboratory Experiment
Košťál, Stanislav ; Vágner, Petr (referee) ; Urbanec, Tomáš (advisor)
The aim of this thesis is to describe the distribution and behavior of selective circuits and methods for their implementation. There are formulas provided for the calculation of the frequency components of selected second-order RLC filters. It further describes the choice of filter frequency components and computing relationships needed for the construction of coils. The work also includes a description and complete information needed for making measurements of the measurement of the RLC band-pass. The annex to this work includes all the materials needed for implementation of laboratory tasks designed to measure using the product.

Input audio preamplifier used for laboratory measurements
Kučera, Ondřej ; Kaller, Ondřej (referee) ; Kratochvíl, Tomáš (advisor)
This article looks at pre-input low-frequency amplifiers for laboratory work. The task was to study, design and build a fully functional pre-input amplifier for use in low frequency audio technology. In each section, we will discuss the various preamps, which are classified according to signal processing parameters. The construction of each amplifier uses discrete components and operational amplifiers. The second part of the article looks at different measuring devices, such as input sensitivity, transfer characteristics and input impedance etc., which would form part of the amplifier.
