(a) Design a four-resistor bias network with the configuration shown in Figure P5.61 to yield \(Q\)-point values of \(I_{C Q}=0.50 \mathrm{~mA}\) and \(V_{C E Q}=2.5 \mathrm{~V}\). The bias voltages are \(V^{+}=3 \mathrm{~V}\) and \(V^{-}=-3 \mathrm{~V}\). The transistor current gain is \(\beta=120\). The voltage across the emitter resistor should be approximately 0.7V.

(b) Replace the designed resistors in part (a) with standard resistors with values closest to the designed values. Determine the resulting \(Q\)-point.
