Tarea 2.1

The document is a quiz on comparators from a course on Electronics II. It contains 8 multiple choice questions about the basic operation and applications of comparator circuits. Specifically, it covers that comparators accept different voltage inputs and provide a digital output, reference voltages are connected to specific input terminals, the reference voltage level must be set appropriately, common comparator ICs like the 311 can operate from single or dual power supplies, and how comparators can be used in applications like temperature monitoring circuits.
