Shortwave power amplifier
Kufa, Jan ; Vařacha, František (referee) ; Prokeš, Aleš (advisor)
The aim of the master´s thesis is to create a high-frequency amplifier with switching power amplifier classes among classes A, B, C with output power of 10 W. The amplifier operates at frequency from 3.5 MHz to 14 MHz. Master´s thesis includes also theoretical analysis, design of lowpass filter and amplifiers and their simulation, mechanical realization and measured parameters of the amplifier.

Doppler blood flow indicator
Byrtus, David ; Čech, Petr (referee) ; Rozman, Jiří (advisor)
Bachelor´s thesis deals with methods for measuring Doppler velocity and blood flow in non-directional system with unmodulated carrier wave, system design indicator of blood flow for a frequency of 4 MHz ultrasound intensity of 100 mW/cm2 and evaluating methods of Doppler signals.
