Belt conveyor - tolerance analysis
Man, Lukáš ; Pokorný, Přemysl (referee) ; Zeizinger, Lukáš (advisor)
The Thesis deals with the tolerance analysis of the factors entering the long-distance belt conveyor of wet sand transport. The Thesis contains a critical research of similar belt conveyors of long-distance transport and a description of main parts of long-distance belt transport. Furthermore, the Thesis includes a calculation according to CSN ISO 5048 and all the standards related to this standard.

The Tolerance Analysis of Filters with CDTA
Miksl, Jan ; Jeřábek, Jan (referee) ; Šotner, Roman (advisor)
The bachelor thesis deals with the concept, design, modeling, tolerance and sensitivity analysis of the KHN filter using CDTA. The first part contains theoretical introduction about filters and their general properties. Secondly, the CDTA element, its block structure, schematic symbol as well as its circuit features are defined. Standard KHN filter structure with operational amplifiers is simulated. Results of this simulation are used for comparison with simulations results of CDTA KHN filter structure. The multifunctional CDTA KHN filter structure is simulated using ideal CDTA models, third-level models and models based on professional macromodels of attainable components (AD 844, MAX 435). Then tolerance and sensitivity analyses are explained and described. The following section discusses ways of modifying the structure and design KHN structure with CDTA models 3rd level. In the last chapter the circuit is optimized using PSpice and the attention is focused on achieving the best possible involvement of the typical characteristics of the elements of tolerance. In conclusion, the results of simulations are evaluated, compared the characteristics of circuit before and after optimization, and mention the advantages and disadvantages of filter elements with CDTA.

Analysis, features and applications of available current mode multipliers
Miksl, Jan ; Jeřábek, Jan (referee) ; Šotner, Roman (advisor)
The diploma thesis deals with analysis, validation, measurement of parameters of the commercially available current multiplies (namely the EL2082 and EL4083) and their applications in practice. Control analysis are carried out in OrCAD PSpice program and compared with values from datasheets. Control analysis are focused on AC and DC characteristics of these active blocks. There are discusses the input impedance, the output impedance, the current gain and the possibility of electronic adjusting. The parameters of the elements were verified by measurements. Proposals for circuit applications (selective circuit, oscillator, frequency filter) with EL2082 and EL4083 are presented and analyzed in the program OrCAD. Three oscillator circuit designs are experimentally tested and the results are compared with the theoretical expectations and simulations in OrCAD. The possibility of electronic control for oscillators is examined. Also the sensitivity and the tolerance analysis are carried out. The constructional details of oscillators are presented at the end of this work.

Applications of multi-output active elements in current-mode
Maňas, Stanislav ; Jeřábek, Jan (referee) ; Šotner, Roman (advisor)
Bachelor's thesis deals with analyzing the characteristics of the block in current mode CCII and its applications. The first part is devoted to the theory of CC block, the theory of CCII block his peripheral involvement and exploration properties. The second part is a third model levels and this is carried out sensitivity and tolerance analysis of individual involvement. The third part is a block CCII surveyed as part of participation frequency filters and oscillators. One involvement has been experimentally tested. At the end of each subsection is obtained by a comparison of the characteristics of individual involvement.
