Weight sensing of beehives with long-term stability
Vozdecký, Martin ; Marcoň, Petr (referee) ; Mikulka, Jan (advisor)
The aim of the thesis is to describe the design of stable measurement of weight in beehives. Work evaluates suitable types of weight sensors and their effect on stability. The main part of the thesis is a custom design of electronic sensing the weight of the beehive and telemetry data to the user. The concept of engagement enables stable measurement of mass loading of independence on the ambient temperature.

Strip thickness measurement device
Vitoslavský, Ondřej ; Petyovský, Petr (referee) ; Macho, Tomáš (advisor)
This work deals with the design of software capable of operating individual components of measuring equipment and acquaintance with these components. These components are analog-digital converter AD7175-2, digital-analog converter DAC8563 and LCD BC- 1602A-YPLEH. It also deals with communication via the Modbus with superior PLC, which has the ability to read data from the measuring device and control the device to a certain extent.

Audio Interface for Embedded PC
Staroň, Martin ; Hanák, Pavel (referee) ; Schimmel, Jiří (advisor)
The scope of my master thesis is a designing computer sound interface including measurement of audio performance. This work is concerning both design analog front - ends and digital support circuits. The sigma delta Analog to Digital (ADC) and Digital to Analog (DAC) converters is included in this conception. Those converters has been made into two separate printed circuit boards. All signal paths in this circuitry are utilizing differential mode that are quoted as balanced among audio engineers. Modern circuit components are used in this design, such as fully differential operational amplifiers, electronically controlled gain preamplifiers, low drop linear stabilizers with low noise level, DC component suppression circuits and low jitter active components. Theoretical part of this thesis contains specification of choosed sound defitions, questioning audio program loudness leveling. Further criteria of suitable active and passive components are included. In this thesis the simulations of fundamental circuits block are meant likewise. Practical part involve complete layout of printed circuit boards of and prototyping. Designed prototype device has wide application usage. It is intended to use not only as industrial computers, but also as dedicated sound converters, measurement cards, mixing consoles, switching matrixes, active loudspeakers, embedded systems.

Audio ADC and DAC for laboratory measurements
Raszka, Dan ; Frýza, Tomáš (referee) ; Kratochvíl, Tomáš (advisor)
This paper describes the design of a laboratory equipment to demonstrate the influence of the sampling frequency and quantization errors on converter. Part of this work is to select appropriate ADC and DAC along with control microprocessor. The proposal contains other functional blocks such as analog input and output filters, LCD display and controls. It deals also with the design of software solutions to control and signal processing.
