Abstract

This thesis deals with the testing of several circuit diagram with gyrator in use. In the electronical circuits using active filters has been verified and tested the involvement of the high-pass and band-pass filter. The second chapter is devoted to the definition of gyrator, his markings and features. The third chapter introduces the gyrator circuit implementations and their distribution. In the next section of thesis has been described what the electric filter is, their distribution and active components suitable for their implementation. Chapter five describes several functional blocks used in the practical part. The sixth chapter deals with the practical part which is focused on the involvement of four different gyrator circuits in combination with the high-pass and band-pass filters involvement. There is determined whether the circuits are working and what are the parameters od all four measurements. The last chapter evaluates the results of measurements and determines the circuit with the best parameters. There are compared the calculated cut-off frequencies and simulated frequency characteristics with practically measured.
