7.42
7.46 (change the 52 V source to 32 V)
7.52 (change the 1 kohm resistor to 6.8 kohm and the 0.025 microF capacitor to 0.2 microF)

7.74.

** Problem 7.74 will be due on Wednesday, April 2. **

4. Please answer the following question for Monday, March 31. Figure 1 contains a slightly more general version of the clock circuit from Lab 4, where Ra and Rb may not be equal. Assume that the op amp is powered so that -10 V <= vout(t) <= +10 V, and let T denote the period of the waveform produced by the oscillator circuit.
