The circuit shown in Figure P 4.8-2 has two inputs, V, and is, and one output vo. The output is related to the inputs by the equation Vo = ai, + bvs where a and b are constants to be determined. Determine the values a and b by (a) writing and solving mesh equations and (b) writing and solving node equations. 9602 120 ww 3292 30 2 Figure P 4.8-2 www Vo
