For the noninverting amplifier shown in Fig. 8.59, R₁= 1 kΩ, and R₂= 5 kΩ. For the op amp, take R_i= 1 MΩ, R_o= 100 Ω, and a_v= 1 × 10⁴. Calculate input resistance, output resistance, loop transmission, and closed-loop gain:

(a) Using the formulas from two-port analysis (Section 8.5).

(b) Using the formulas from return-ratio analysis (Section 8.8).
