Switchable filter for UHF band
Sedlák, Milan ; Čáp, Martin (referee) ; Drexler, Petr (advisor)
The bachelor thesis deals with the design of multi-channel switchable filter for ultra high frequency band. The theoretical part focuses on a basic features and principles of the realization of frequency filters and high frequency switches. The practical part focuses on the selection of appropriate components and complete design of switchtable signal filter.
Switchable Filter For UHF Band
Sedlák, Milan
The contribution deals with the design of a multi-channel switchable filter for ultra high frequency band. The device is primarily designed for the system of sensors which are used for detection of the electromagnetic pulses. They are emitted by the partial discharges in power transformers as a consequence of aging of the dielectric. The main task of the multi-channel switchable filter is to ensure better reliability of the entire system by filtering of undesirable signals with lower frequencies content which are usually products of the external and internal disturbance.
