An experimental study of thin-film uniform R0-C0-KR0 structure as null filter configurations

The present work deals with the experimental study of two well known null filters derived as subnetworks of thin-film distributed parameter R0-C0-KR0 structure. It is also shown here that the filters can be made tunable, simply by connecting a variable lumped resistor in series with the grounded terminal. The results of experimental study are presented graphically.
