15.19 Consider the circuit of Fig. 15.8 with the 50- kΩ potentiometer replaced with two fixed resistors: 10 kΩ between the op amp’s negative input and ground, and 15 kΩ. Modeling each diode as a 0.65-V battery in series with a 100-Ω resistance, find the peak-to-peak amplitude of the output sinusoid.
