On an integral equation approach to the steady-state problem in nonlinear circuits

Recently /spl lsqb/see ibid., vol. 39, p.744-5, 1992/spl rsqb/ an efficient method for computing the steady-state response in nonlinear circuits was proposed. Additional background information has come to the attention of the authors regarding the general framework of the described research. They wish to point out that Sandberg /spl lsqb/see ibid., vol. CAS-31, no. 8, p. 689-701, 1984/spl rsqb/ has also used the "integral equation" description to study nonlinear systems.<
