Adaptive frequency filter

Abstract

ABSTRACT My diploma thesis is called „Adaptive frequency filter“ and I divided it into four parts. I read up basic qualities of selective functional block 1. and 2. rate of ARC filters at the beginning. Next, I processed possibilities of analogue and digital control of active RC filters´ parameters. The second part deals with a suitable choice of universal functional block 2. rate realizing more types of transfer functions. To the effect I chose Ackerberg – Mossberg´s wiring of universal filter, and I made a designs of particular parameters for it. In the third part I focused on simulations of this filter by the help of the programme Spice for different values and operating opportunities of its parameters. At the close of my diploma work I created a functional sample and I made many experimental metering with both analogue and digital control
