NOTE: Due to a difference between our lab equipment and what is specified in this lab, there are numerous adjustments and changes made to the schematics and tables in the handouts. Follow the modified directions on the lab sheet very carefully.
This week we will investigate a circuit which will create a PWM (Pulse-Width Modulated) output. You can download a copy of the experiment here in the Registered Users Only area. A hard copy will be provided for you in class on Monday, 2/11. Additional copies will be available in the lab area.
This circuit uses the LM311 Precision Comparator which most of you used last semester for the Thermostat Temperature Comparator experiment, along with the LM34. There are additional handouts to explain the operation of the LM311 and the actual LM311 Data Sheet.
