(choose chapter or problem)

The circuit shown in Figure P 4.3-8 has two inputs, \(v_1\) and \(v_2\), and one output, \(v_0\). The output is related to the input by the equation

                                                             \(v_0=a v_1+b v_2\)

where a and b are constants that depend on \(R_1, R_2\), and \(R_3\).

(a) Determine the values of the coefficients a and b when \(R_1=10 \Omega, R_2=40 \Omega\), and \(R_3=8 \Omega\).

(b) Determine the values of the coefficients a and b when \(R_1=R_2\) and \(R_3=R_1 \| R_2\).
