Exercise 7. Sketch the input-output characteristic curve of the circuit in Figure 5. The input waveform is provided by \( V_{1} . V_{2}=2 \underline{\underline{V}} \) Figure 5: Inverting Comparator with \( R_{L}=1.2 \mathrm{~K} \Omega \). The supply voltages \( V_{P} \) and \( V_{N} \) are \( 15 \mathrm{~V} \) and the saturation voltage is \( V_{O \mathrm{sar}}=\pm 13 \). Exercise 8. Draw the output waveform for Figure 5 given the input \( V_{1} \) in Figure 6. Figure 6: Input Waveform applied to Figure 5 Exercise \( 9 . \quad \) Find \( V_{+} \)in Figure 7. Figure 7: Voltage divider with \( V_{1}=8 \underline{\underline{V}} R_{1}=12.0 \mathrm{~K} \Omega \) and \( R_{2}=43.0 \mathrm{~K} \Omega \) Exercise 10. Find \( V_{+} \)in Figure 8 when the resistance of the LDR is low \( \left(R=0.22 K \Omega\right. \), bright light, ans. \( V_{+}=\underline{\underline{0.13 V})} \) and when the resistance of the LDR is high \( (R=1.0 \mathrm{M} \Omega \), dark). Figure 8: Voltage divider with \( V_{1}=7 \mathrm{~V} \) and \( R_{1}=12.0 \mathrm{~K} \Omega \).
