An Experimental Study of the Effect of External Resistor on the Null Frequency of Ro-Co-KRo Structures

Page 374 | Received 20 Dec 1977, Published online: 11 Jul 2015
 

Abstract

A three-layer R0-C0-KR0 uniformly-distributed-parameter structure with an external variable resistor connected in series with the common grounded terminal is studied experimentally as a variable-frequency null filter. The results indicating null frequency and null depth as a function of external resistor are presented graphically.
