Comment on “GB-R impedances: new approach to impedance simulation” [and reply]

For the original article see ibid., vol. 31, no. 9, p. 689-90 (1995). The commenter gives further insight into the circuits proposed in the aforementioned paper by Serrano and Carlosena and provides two equivalent simplified circuits. In reply the authors substantially agree with the comment but go on to point out several advantages of retaining their circuit configurations
