Analysis of the acoustic signal to detect the speed of vehicles
Koníčková, Tereza ; Beneš, Petr (referee) ; Klusáček, Stanislav (advisor)
The aim of this Bachelor thesis is to create software for sound signal analysis of a passing car with the aim to determine the driving speed. This work describes single methods of a car velocity measurement and it is submitting a new method of velocity measurement with using the Doppler principle at sound signal analysis. My work proved, that it is possible to use this method to determine the speed of vehicles.
Measurements by sampling computer card - laboratory task
Tomaštík, Roman ; Havránek, Zdeněk (referee) ; Dřínovský, Jiří (advisor)
This thesis focuses on the measurement with the help of sampling cards and determination of the basic parameters of the measured signal. There will be described basic characteristics of the used card Alazartech ATS860- 256M and brief description of the programming languages which will control the cards. In these environments there were the created driving programs for the operation of these cards. Main measuring program was created in the language C\C++, that shall work as oscilloscope and the same time as spectral analyzer. This programme will determine basic characteristics of the measured signal. Further there will be created simple preparation for memasuring with this card. In the conclusion of this thesis will create instrutions for laboratory exercise.
