1. One way to generate a sine wave using a microcontroller is using a lookup table and
interrupts. An internal timer interrupts the processor periodically. In the ISR, the
processor reads an entry from the table and writ

a. What is the number of resistors needed for the resistor string?
The resistor string needs to generate 212 -1 distinct steps of the reference voltage
Vref, so 212 resi
