Design of filters in current, voltage and hybrid modes with OA, using autonomous curcuits
Jašek, František ; Minarčík, Martin (referee) ; Vrba, Kamil (advisor)
This bachelor‘s thesis describes the procedure of design of frequency filters with operational amplifier using autonomous circuit. At first there is the procedure of an inference common and autonomous circuits with operational amplifier, of which they are follow on derived know and unknown engagement of frequency filters in voltage, current and hybrid mode. In all these inference frequency filters were determine a transmission function, according them is evidently about which frequency filters is discussed (low pass, high pass, band pass, band stop). The derived filter circuits are then selected two unknown involvement, which is set out in detail the procedure in the design of the frequency filter. Both suggestion circuits was verified by a simulation which results are noticed in this thesis and sequentially was made an experimental verified by mounting product in SMD. On this product was made a metering of a transmission and phase frequency characterization which was recorded in the graph. In fine there is a description of propriety of suggestion frequency filters for a practically use in this production.
