• For the circuit in Figure 1, assume that the voltage drop across the infrared emitter is 1.3 V. Determine the value of RE that will limit the emitter current to a maximum of 50 mA.

• For the circuit in Figure 1, assume RX = 10 kΩ and VS = 5 V. Using the equation given in the introduction section, determine the value of RF needed to implement the Schmitt Trigger with a spread or hysteresis value between 0.5 V to 1 V. Use only standard resistor values in your lab kit.

• VREF must equal 2.5 V. In Lab 7, a buffer op-amp was used to provide this voltage. You may use the same op-amp to provide VREF to both Modules 2 and 3. Use the same values of ROUT, R1 and R2 that you used in Labs 6 and 7.
